Item 1. Business


The business of State Street Corporation and its subsidiaries is further
described in the "Financial Review" section of State Street Corporation's 1998
Annual Report to Stockholders, which section comprises Management's Discussion
and Analysis of Financial Condition and Results of Operation for the
Corporation; such description and information and analysis is included in
Exhibit 13 of this report and is incorporated by reference.


General Development of Business


State Street Corporation ("State Street" or the "Corporation") is a bank holding
company organized under the laws of the Commonwealth of Massachusetts and is one
of the world's leading specialists in serving institutional investors and
provides a full range of products and services for large portfolios of
investment assets.


State Street was organized in 1970 and conducts its business principally through
its subsidiary, State Street Bank and Trust Company ("State Street Bank" or the
"Bank"), and traces its beginnings to the founding of the Union Bank in 1792.
The charter under which State Street Bank now operates was authorized by a
special act of the Massachusetts Legislature in 1891, and its present name was
adopted in 1960.


State Street is a market leader in the businesses on which it focuses, services
for institutional investors and investment management, with $4.8 trillion of
assets under custody and $485 billion of assets under management at year-end
1998. Customers include mutual funds and other collective investment funds,
corporate and public pension funds, corporations, unions and non-profit
organizations in and outside of the United States. For information as to
non-U.S. activities, refer to Note V which appears in the Notes to Financial
Statements in State Street's 1998 Annual Report to Stockholders. Such
information is incorporated by reference.


Services are provided from 30 offices in the United States, as well as from
offices in Australia, Austria, Belgium, Canada, Cayman Islands, Chile, Czech
Republic, France, Germany, Ireland, Japan, Luxembourg, Netherlands Antilles,
Netherlands, New Zealand, People's Republic of China, Russia, Singapore, South
Korea, Switzerland, Taiwan, United Arab Emirates and the United Kingdom. State
Street's executive offices are located at 225 Franklin Street, Boston,
Massachusetts.


Lines of Business


State Street reports three lines of business: Services for Institutional
Investors, Investment Management and Commercial Lending. In 1998, 67% of income
before income taxes came from services for institutional investors, 19% came
from commercial lending and 14% from investment management. For additional
information on State Street's lines of business, see pages 22 and 23 of State
Street's 1998 Annual Report to Stockholders, under the caption "Lines of
Business", which information is incorporated by reference.


Services for Institutional Investors. Services for institutional investors
includes accounting, custody, daily pricing and information services for
investment portfolios. Customers include mutual funds and other collective
investment funds, corporate and public pension plans, corporations, investment
managers, non-profit organizations, unions, and other holders of investment
assets. Institutional investors are offered other State Street services,
including foreign exchange, cash management, securities lending, fund
administration, recordkeeping, banking services, and deposit and short-term
investment facilities. These services support institutional investors in
developing and executing their strategies, enhancing their returns, and
evaluating and managing risk.


With $2.1 trillion of mutual fund assets under custody, State Street is the
largest mutual fund custodian and accounting agent in the United States. State
Street began providing mutual fund services in 1924. Customers who sponsor the
U.S. mutual funds that State Street services include investment companies,
broker/dealers, insurance companies and others. In addition, State Street
services offshore mutual funds and collective investment funds in other
countries.


State Street is distinct from other mutual fund service providers because
customers make extensive use of a number of related services in addition to
custody. Additional services include fund accounting and administration, daily
pricing, accounting for multiple classes of shares, master/feeder accounting,
and services for offshore funds and local funds in locations outside the United
States. Shareholder services are provided through an affiliate, Boston Financial
Data Services, Inc.


State Street began servicing pension assets in 1974, and now has $2.3 trillion
of pension, insurance and other investment pool assets under custody for U.S.
customers. State Street has a leading share of the market for servicing
tax-exempt assets for corporate and public funds in the United States. Services
include custody, portfolio accounting, securities lending, information and


                                       1
<PAGE>

Item 1. Business (continued)

other related services for retirement plans and other financial asset portfolios
of corporations, public funds, investment managers, non-profit organizations,
unions and others. State Street provides global and domestic custody and
custody-related services for $362 billion in assets for customers outside the
United States.


State Street provides foreign exchange services to institutional investors
worldwide. These services include currency trading and currency research, risk
management and electronic execution services. State Street is a securities
lending agent providing collateral management and lending of securities issued
in 30 countries, acting as agent between institutional investors and
broker/dealers worldwide. State Street also provides repurchase agreements and
deposit services for the short-term cash needs associated with customers'
investment activities. Trading and arbitrage operations are conducted with
government securities and other financial instruments.


Investment Management. State Street was a pioneer in the development of domestic
and international index funds. State Street offers an extensive range of
investment management services, including investment management for
corporations, public funds and other institutional investors; administration and
investment services for defined contribution and other employee benefit
programs; and investment management and other financial services for
high-net-worth individuals. These services are offered through State Street
Global Advisors ("SSgA[RegTM]"). SSgA offers a broad array of investment
strategies, including passive, enhanced and active management using quantitative
and fundamental methods for both global equities and global fixed income
securities. SSgA is a leading trustee and money manager for individuals. At
year-end 1998, institutional and personal trust assets under management totaled
$485 billion. Additionally, SSgA provides record-keeping and other services
attendant to its investment management activities, including services for 2.6
million defined contribution plan participants as of year-end 1998. SSgA has
offices worldwide, including offices in the following cities: Boston, Hong Kong,
Tokyo, London, Montreal, Munich, Paris and Sydney. In the United States, SSgA is
the largest manager of tax-exempt assets, the third-largest manager of defined
contribution plan assets and the third-largest manager of total assets.


Commercial Lending. State Street provides lending and other banking services for
regional middle-market companies, companies in selected industries and
institutional investor customers and provides lease financing to selected
industries. Other banking services include cash management and deposit services.


Competition


State Street operates in a highly competitive environment in all areas of its
business on a worldwide basis, including services to institutional investors,
investment management and commercial lending. In addition to facing competition
from other deposit-taking institutions, State Street faces competition from
investment management firms, private trustees, insurance companies, mutual
funds, broker/dealers, investment banking firms, law firms, benefits
consultants, leasing companies, and business service and software companies. As
State Street expands globally, additional sources of competition are
encountered.


State Street believes there are certain key competitive considerations in these
markets, specifically, for investment asset servicing: price, quality of
service, efficiencies from scale and technological expertise, and quality and
scope of sales and marketing; for investment management: expertise, experience,
and the availability of related service offerings; and for commercial lending:
price and experience.


State Street's competitive success primarily depends upon its ability to
continue to develop and market new and innovative services and to adopt or
develop new technologies to bring new services to market in a timely fashion at
competitive prices; and to continue and expand its relationships with existing
and new customers.


Employees


At December 31, 1998, State Street had 16,816 employees, of whom 16,266 were
full-time.


Regulation and Supervision


State Street is registered with the Board of Governors of the Federal Reserve
System (the "Board") as a bank holding company pursuant to the Bank Holding
Company Act of 1956, as amended (the "Act"). The Act, with certain exceptions,
limits the activities that may be engaged in by State Street and its non-bank
subsidiaries, which include non-bank companies for which State Street owns or
controls more than 5% of a class of voting shares, to those which are deemed by
the Board to be so closely related to banking or managing or controlling banks
as to be a proper incident thereto. In making such determination, the Board must
consider whether the performance of any such activity by a subsidiary of State
Street can reasonably be expected to produce


                                       2
<PAGE>

Item 1. Business (continued)

benefits to the public, such as greater convenience, increased competition or
gains in efficiency. These benefits must outweigh possible adverse effects, such
as undue concentration of resources, decreased or unfair competition, conflicts
of interest or unsound banking practices. The Board is authorized to
differentiate between activities commenced de novo and those commenced by the
acquisition in whole or in part of a going concern. The Board may order a bank
holding company to terminate any activity or its ownership or control of a
non-bank subsidiary if the Board finds that such activity or ownership or
control constitutes a serious risk to the financial safety, soundness or
stability of a subsidiary bank and is inconsistent with sound banking principles
or statutory purposes. In the opinion of management, all of State Street's
present subsidiaries are within the statutory standard or are otherwise
permissible. The Act also requires a bank holding company to obtain prior
approval of the Board before it may acquire substantially all the assets of any
bank or ownership or control of more than 5% of the voting shares of any bank.


Bank holding companies, such as State Street, are subject to Federal Reserve
Board risk-based capital guidelines that require a minimum 8% ratio of total
capital to risk-weighted assets (including certain off-balance-sheet items) and
market-risk equivalents. At least 50% of total capital must consist of common
stockholders' equity, minority interest, non-cumulative perpetual preferred
stock, and a limited amount of cumulative perpetual preferred stock, less
disallowed intangibles and other adjustments ("Tier 1 capital"). The remainder
may consist of subordinated debt, other preferred stock, certain other
instruments and a limited amount of loan loss reserves and the unrealized gain
on available-for-sale equity securities ("Tier 2 capital"). At December 31,
1998, State Street's consolidated Tier 1 capital and total capital ratios were
14.1% and 14.4%, respectively.


In addition, bank holding companies are subject to Federal Reserve Board minimum
leverage ratio guidelines. These guidelines provide for a minimum ratio of Tier
1 capital to total average assets (the "leverage ratio") of 3% for bank holding
companies that meet certain specified criteria, including those having the
highest regulatory rating. All other bank holding companies generally are
required to maintain a leverage ratio of at least 3% plus an additional cushion
of 100 to 200 basis points. State Street's leverage ratio at December 31, 1998,
was 5.4%. The guidelines also provide that bank holding companies experiencing
internal growth or making acquisitions will be expected to maintain strong
capital positions substantially above the minimum supervisory levels without
significant reliance on intangible assets. The Federal Reserve Board has
indicated that it will also consider a "tangible Tier 1 capital leverage ratio"
(deducting all intangibles) and other indicia of capital strength in evaluating
proposals for expansion or new activities.


State Street Bank is subject to similar risk-based and leverage capital
requirements. State Street Bank was in compliance with the applicable minimum
capital requirements as of December 31, 1998. Neither State Street nor State
Street Bank has been advised of any specific minimum leverage ratio requirement
applicable to it.


Failure to meet capital requirements could subject a bank to a variety of
enforcement actions, including the termination of deposit insurance by the FDIC,
and to certain restrictions on its business, which are described further in this
section.


State Street and its non-bank subsidiaries are affiliates of State Street Bank
under the federal banking laws, which impose certain restrictions on transfers
of funds in the form of loans, extensions of credit, investments or asset
purchases by State Street Bank to State Street and its non-bank subsidiaries.
Transfers of this kind to State Street and its non-bank subsidiaries by State
Street Bank are limited to 10% of State Street Bank's capital and surplus with
respect to each affiliate and to 20% in the aggregate, and are subject to
certain collateral requirements. A bank holding company and its subsidiaries are
prohibited from engaging in certain tie-in arrangements in connection with any
extension of credit or lease or sale of property or furnishing of services.
Federal law also provides that certain transactions with affiliates must be on
terms and under circumstances, including credit standards that are substantially
the same, or at least as favorable to the institution as those prevailing at the
time for comparable transactions involving other non-qualified companies or, in
the absence of comparable transactions, on terms and under circumstances,
including credit standards, that in good faith would be offered to, or would
apply to, nonaffiliated companies. This is commonly referred to as an
"arms-length transaction". The Board has jurisdiction to regulate the terms of
certain debt issues of bank holding companies.


State Street, State Street Bank and their affiliates are also subject to
restrictions with respect to issuing, floating and underwriting, or publicly
selling or distributing, securities in the United States. State Street and its
affiliates are able to underwrite and deal in specific categories of securities,
including U.S. government and certain agency, state, and municipal securities.


Under Federal Reserve Board policy, a bank holding company is required to act as
a source of financial and managerial strength to its subsidiary banks. Under
this policy, State Street is expected to commit resources to its subsidiary
banks in circumstances where it might not do so absent such policy. In the event
of a bank holding company's bankruptcy, any commitment by the bank holding
company to a federal bank regulatory agency to maintain the capital of a
subsidiary bank will be assumed by the bankruptcy trustee and entitled to a
priority payment.


                                       3
<PAGE>

Item 1. Business (continued)

The primary federal banking agency responsible for regulating State Street and
its subsidiaries, including State Street Bank, for both domestic and
international operations is the Federal Reserve System. State Street is also
subject to the Massachusetts bank holding company statute. The Massachusetts
statute requires prior approval by the Massachusetts Board of Bank Incorporation
for the acquisition by State Street of more than 5% of the voting shares of any
additional bank and for other forms of bank acquisitions.


State Street's banking subsidiaries are subject to supervision and examination
by various regulatory authorities. State Street Bank is a member of the Federal
Reserve System and the Federal Deposit Insurance Corporation (the "FDIC") and is
subject to applicable federal and state banking laws and to supervision and
examination by the Federal Reserve Bank of Boston, as well as by the
Massachusetts Commissioner of Banks, the FDIC, and the regulatory authorities of
those countries in which a branch of State Street Bank is located. Other
subsidiary trust companies are subject to supervision and examination by the
Office of the Comptroller of the Currency, other offices of the Federal Reserve
System or by the appropriate state banking regulatory authorities of the states
in which they are located. State Street's non-U.S. banking subsidiaries are also
subject to regulation by the regulatory authorities of the countries in which
they are located. The capital of each of these banking subsidiaries is in excess
of the minimum legal capital requirements as set by those authorities.


The Financial Institutions Reform, Recovery and Enforcement Act of 1989
("FIRREA") broadened the enforcement powers of the federal banking agencies,
including increased power to impose fines and penalties, over all financial
institutions, including bank holding companies and commercial banks. As a result
of FIRREA, State Street Bank and any or all of its subsidiaries can be held
liable for any loss incurred by, or reasonably expected to be incurred by, the
FDIC after 1989, in connection with (a) the default of State Street Bank or any
other subsidiary bank or (b) any assistance provided by the FDIC to State Street
Bank or any other subsidiary bank in danger of default. The Crime Control Act of
1990 further broadened the enforcement powers of the federal banking agencies in
a significant number of areas.


The Federal Deposit Insurance Corporation Improvement Act of 1991 ("FDICIA") has
as its primary objectives to recapitalize the Bank Insurance Fund and strengthen
the regulation and supervision of financial institutions.


Pursuant to FDICIA, each federal banking agency has adopted prompt corrective
action regulations for the institutions that it regulates. The statute requires
or permits the agencies to take certain supervisory actions when an insured
depository institution falls within one of five specifically enumerated capital
categories. It also restricts or prohibits certain activities and requires the
submission of a capital restoration plan when an insured institution becomes
undercapitalized. The regulations establish the numerical limits for five
capital categories and establish procedures for issuing and contesting prompt
corrective action directives. To be within the category "well capitalized", an
insured depository institution must have a total risk-based capital ratio of
10.0% or greater, a Tier 1 risk-based capital ratio of 6.0% or greater, and a
leverage ratio of 5.0% or greater and the institution must not be subject to an
order, written agreement, capital directive, or prompt corrective action
directive to meet specific capital requirements. An insured institution is
"adequately capitalized" if it has a total risk-based capital ratio of 8.0% or
greater, a Tier 1 risk-based capital ratio of 4.0% or greater, and a leverage
ratio or 4.0% or greater (or a leverage ratio of 3.0% or greater if the
institution has a composite rating of "1" under the regulatory rating system).
The final three capital categories are levels of undercapitalized, which trigger
mandatory statutory provisions. While other factors in addition to capital
ratios determine an institution's capital category, State Street Bank's capital
ratios were within the "well-capitalized" category at December 31, 1998. For
further information as to the Corporation's capital position and capital
adequacy, refer to the Liquidity and Capital Resources portion of the Financial
Review section and to Note K to the Notes to Consolidated Financial Statements
which appear in State Street's 1998 Annual Report to Stockholders.
Such information is incorporated by reference.


The Federal Reserve Board adopted a final rule, as required by FDICIA,
prescribing standards that will limit the risks posed by an insured depository
institution's exposure to any other depository institution. Banks are required
to develop written policies and procedures to monitor credit exposure to other
banks, and to limit exposure to "undercapitalized" banks to 25% of total
capital.


As required by FDICIA, the FDIC adopted a regulation that permits only well
capitalized banks, and adequately capitalized banks that have received waivers
from the FDIC, to accept, renew or rollover brokered deposits. Regulations have
also been adopted by the FDIC to limit the activities conducted as a principal
by, and the equity investments of, state-chartered banks to those permitted for
national banks. Banks may apply to the FDIC for approval to continue to engage
in permitted investments and activities.


Other FDICIA regulations adopted require independent audits, an independent
audit committee of the bank's board of directors, stricter truth-in-savings
provisions and standards for real estate lending. FDICIA amended deposit
insurance coverage, and the FDIC have implemented a rule specifying the
treatment of accounts to be insured up to $100,000.


                                       4
<PAGE>

Item 1. Business (continued)

Under other provisions of FDICIA, the federal banking agencies have adopted
safety and soundness standards for banks in a number of areas including:
internal controls, internal audit systems, information systems, credit
underwriting, interest rate risk, executive compensation and minimum earnings.
The agencies have also revised risk-based capital standards to take into account
interest rate risk, as required by FDICIA.


Legislation enacted as part of the Omnibus Budget Reconciliation Act of 1993
provides that deposits in U.S. offices and certain claims for administrative
expenses and employee compensation against a U.S. insured depository institution
which has failed will be afforded a priority over other general unsecured
claims, including deposits in non-U.S. offices and claims under non-depository
contracts in all offices, against such an institution in the "liquidation or
other resolution" of such an institution by any receiver. Accordingly, such
priority creditors (including FDIC, as the subrogee of insured depositors) of
State Street Bank will be entitled to priority over unsecured creditors in the
event of a "liquidation or other resolution" of such an institution.


Dividends


As a bank holding company, State Street is a legal entity separate and distinct
from State Street Bank and its other non-bank subsidiaries. The right of State
Street to participate as a stockholder in any distribution of assets of State
Street Bank upon its liquidation or reorganization or otherwise is subject to
the prior claims by creditors of State Street Bank, including obligations for
federal funds purchased and securities sold under repurchase agreements, as well
as deposit liabilities. Payment of dividends by State Street Bank is subject to
provisions of the Massachusetts banking law which provides that dividends may be
paid out of net profits provided (i) capital stock and surplus remain
unimpaired, (ii) dividend and retirement fund requirements of any preferred
stock have been met, (iii) surplus equals or exceeds capital stock, and (iv)
there are deducted from net profits any losses and bad debts, as defined, in
excess of reserves specifically established therefore. Under the Federal Reserve
Act, the approval of the Board of Governors of the Federal Reserve System would
be required if dividends declared by the Bank in any year would exceed the total
of its net profits for that year combined with retained net profits for the
preceding two years, less any required transfers to surplus. Under applicable
federal and state law restrictions, at December 31, 1998, State Street Bank
could have declared and paid dividends of $979 million without regulatory
approval. Future dividend payments of the Bank and non-bank subsidiaries cannot
be determined at this time.


Economic Conditions and Government Policies


Economic policies of the government and its agencies influence the operating
environment of State Street. Monetary policy conducted by the Federal Reserve
Board directly affects the level of interest rates and overall credit conditions
of the economy. Policy is applied by the Federal Reserve Board through open
market operations in U.S. government securities, changes in reserve requirements
for depository institutions, and changes in the discount rate and availability
of borrowing from the Federal Reserve. Government regulations of banks and bank
holding companies are intended primarily for the protection of depositors of the
banks, rather than of the stockholders of the institutions.


Factors Affecting Future Results


From time to time, information provided by State Street, statements made by its
employees, or information included in its filings with the Securities and
Exchange Commission (including this Form 10-K), may contain statements which are
not historic facts (so-called "forward looking statements"), including
statements about the Corporation's confidence and strategies and its expectation
about revenues and market growth, new technologies, services and opportunities,
and earnings. These statements may be identified by such forward looking
terminology as "expect", "look", "believe", "anticipate", "may", "will", or
similar statements or variations of such terms. These forward-looking statements
involve certain risks and uncertainties which could cause actual results to
differ materially. Factors that may cause such differences include, but are not
limited to, the factors discussed in this section and elsewhere in this Form
10-K. Each of these factors, and others, are also discussed from time to time in
the Corporation's other filings with the Securities and Exchange Commission,
including its reports on Form 10-Q.


Cross-border investing. Increases in cross-border investing by customers
worldwide benefit State Street's revenue. Future revenue may increase or
decrease depending upon the extent of increases or decreases in cross-border
investments made by customers or future customers.


Savings rate of individuals. State Street benefits from the savings of
individuals that are invested in mutual funds or in defined contribution plans.
Changes in savings rates or investment styles may affect revenue.

Item 1. Business (continued)

Value of worldwide financial markets. As worldwide financial markets increase or
decrease in value, State Street's opportunities to invest and service financial
assets may change. Since a portion of the Corporation's fees are based on the
value of assets under custody and management, fluctuations in worldwide
securities market valuations will affect revenue.


Dynamics of markets served. Changes in markets served, including the growth rate
of U.S. mutual funds, the pace of debt issuance, outsourcing decisions, and
mergers, acquisitions and consolidations among customers and competitors, can
affect revenue. In general, State Street benefits from an increase in the volume
of financial market transactions serviced.


State Street provides services worldwide. Global and regional economic factors
and changes or potential changes in laws and regulations affecting the
Corporation's business, including volatile currencies and changes in monetary
policy, and social and political instability, could affect results of
operations.


Interest rates. Market interest rate levels, the shape of the yield curve and
the direction of interest rate changes affect net interest revenue as well as
fiduciary compensation from securities lending. All else being equal, in the
short term, State Street's net interest revenue benefits from falling interest
rates and is negatively affected by rising rates because interest-bearing
liabilities reprice sooner than interest-earning assets.


Volatility of currency markets. The degree of volatility in foreign exchange
rates can affect the amount of foreign exchange trading revenue. In general,
State Street benefits from currency volatility.


Pace of pension reform. State Street expects to benefit from worldwide pension
reform that creates additional pools of assets that use custody and related
services and investment management services. The pace of pension reform may
affect the pace of revenue growth.


Pricing/competition. Future prices the Corporation is able to obtain for its
products may increase or decrease from current levels depending upon demand for
its products, its competitors' activities, and the introduction of new products
into the marketplace.


Pace of new business. The pace at which existing and new customers use
additional services and assign additional assets to State Street for management
or custody will affect future results. State Street believes that uncertainties
resulting from the Year-2000 issues could have an impact on new business for
1999 such that customers and potential customers of State Street will be less
inclined in the second half of 1999 to consider changing their business
relationships.


Business mix. Changes in business mix, including the mix of U.S. and non-U.S.
business, may affect future results.


Rate of technological change. Technological change creates opportunities for
product differentiation and reduced costs, as well as the possibility of
increased expenses. State Street's financial performance depends in part on its
ability to develop and market new and innovative services and to adopt or
develop new technologies that differentiate State Street's products or provide
cost efficiencies.


There are risks inherent in this process. These include rapid technological
change in the industry, the Corporation's ability to access technical and other
information from customers, and the significant and ongoing investments required
to bring new services to market in a timely fashion at competitive prices.
Further, there is risk that competitors may introduce services that could
replace or provide lower-cost alternatives to State Street's services.


State Street uses appropriate trademark, trade secret, copyright and other
proprietary rights procedures to protect its technology, and has applied for a
limited number of patents in connection with certain software programs. The
Corporation believes that patent protection is not a significant competitive
factor and that State Street's success depends primarily upon the technical
expertise and creative abilities of its employees and the ability of the
Corporation to continue to develop, enhance and market its innovative business
processes and systems. However, in the event a third-party asserts a claim of
infringement of its proprietary rights, obtained through patents or otherwise,
against the Corporation, State Street may be required to spend significant
resources to defend against such claims, develop a non-infringing program or
process, or obtain a license to the infringed process.


Year 2000 modifications. The costs and projected completion dates for State
Street's Year-2000 program are estimates. Factors that may cause material
differences include the availability and cost of systems and other personnel,
non-compliance of third-party providers, and similar uncertainties. If necessary
modifications and conversions are not completed in time, the Year-2000 issue
could affect State Street's performance.

Item 1. Business (continued)

Acquisitions and alliances. Acquisitions of complementary businesses and
technologies, and development of strategic alliances are an active part of State
Street's overall business strategy, and the Corporation has completed several
acquisitions and alliances in recent years. However, there can be no assurance
that services, technologies, key personnel, and businesses of acquired companies
will be effectively assimilated into State Street's business or service
offerings or that alliances will be successful.


European Economic and Monetary Union. The move to a common currency could affect
foreign exchange volumes and the level of deposits denominated in the euro or
the legacy currencies.

Loans are evaluated on an individual basis to determine the appropriateness of
renewing each loan. State Street does not have a general rollover policy.
Unearned revenue included in loans was $1 million for each of the years ended
December 31, 1998 and 1997.


Non-Accrual Loans


It is State Street's policy to place loans on a non-accrual basis when they
become 60 days past due as to either principal or interest, or when in the
opinion of management, full collection of principal or interest is unlikely.
Loans eligible for non-accrual, but considered both well secured and in the
process of collection, are treated as exceptions and may be exempted from
non-accrual status. When the loan is placed on non-accrual, the accrual of
interest is discontinued and previously recorded but unpaid interest is reversed
and charged against net interest revenue. Past due loans are loans on which
principal or interest payments are over 90 days delinquent, but where interest
continues to be accrued.


Non-accrual loans totaled $12 million, $2 million, $12 million, $16 million and
$23 million as of December 31, 1998 through 1994, respectively. There were no
non-accrual loans to non-U.S. customers in 1998, less than $1 million in 1997,
$6 million in 1996, and there were none in 1995 and 1994.


Past due loans totaled less than $1 million as of December 31, 1998 through
1994. Past due loans included loans to non-U.S. customers for less than $1
million in 1998 and 1997, and none for the years 1996 through 1994.


The interest revenue for 1998 which would have been recorded related to these
non-accrual loans is less than $1 million for domestic loans. The interest
revenue that was recorded on these non-accrual loans was less than $1 million,
all of which relates to domestic loans.

State Street establishes an allowance for loan losses to absorb probable credit
losses. Management's review of the adequacy of the allowance for loan losses is
ongoing throughout the year and is based, among other factors, on previous loss
experience, current economic conditions and adverse situations that may affect
the borrowers' ability to repay, timing of future payments, estimated value of
the underlying collateral and the performance of individual credits in relation
to contract terms, and other relevant factors.


While the allowance is established to absorb probable losses inherent in the
total loan portfolio, management allocates the allowance for loan losses to
specific loans, selected portfolio segments and certain off-balance sheet
exposures and commitments. Adversely classified loans in excess of $1 million
are individually reviewed to evaluate risk of loss and assigned a specific
allocation of the allowance. The allocations are based on an assessment of
potential risk of loss and include evaluations of the borrowers' financial
strength, discounted cash flows, collateral, appraisals and guarantees. The
allocations to portfolio segments and off-balance sheet exposures are based on
management's evaluation of relevant factors, including the current level of
problem loans and current economic trends. These allocations are also based on
subjective estimates and management judgment, and are subject to change from
quarter-to-quarter. In addition, a portion of the allowance remains unallocated
as a general reserve for the entire loan portfolio. The general reserve is based
upon such factors as portfolio concentration, historical losses and current
economic conditions.


The provision for loan losses is a charge to earnings for the current period
which is required to maintain the total allowance at a level considered adequate
in relation to the level of risk in the loan portfolio. The provision for loan
losses was $17 million and $16 million in 1998 and 1997, respectively.



At December 31, 1998, loans comprised 13% of State Street's assets. State
Street's loan policies limit the size of individual loan exposures to reduce
risk through diversification.

Item 1. Business (continued)

For 1998, net charge-offs were $16 million versus net charge-offs of $6 million
in 1997. Net charge-offs for 1998, as a percentage of average loans, were .24%
compared to net charge-offs of .11% for 1997.


At December 31, 1998, total non-performing assets were $16 million, a $10
million increase from year-end 1997. Non-performing assets include $12 million
and $2 million of non-accrual loans at year-end 1998 and 1997, respectively, and
$4 million of other real estate owned for both 1998 and 1997.


At December 31, 1998, the allowance for loan losses was $84 million, or 1.34% of
total loans. This compares with an allowance of $83 million, or 1.49% of total
loans a year ago. In 1998, the measures of credit quality continued to be
satisfactory, largely due to favorable U.S. economic conditions. State Street
expects these measures of credit quality to continue to remain satisfactory in
1999. Actual results may differ materially from these forward looking statements
due to deterioration in the economic conditions and other unforeseen factors.


Cross-Border Outstandings


Countries within which State Street has cross-border outstandings (primarily
deposits and letters of credit to banks and other financial institutions) of at
least 1% of its total assets at December 31, were as follows:

Item 2. Properties

State Street's headquarters are located in the State Street Bank Building, a
34-story building at 225 Franklin Street, Boston, Massachusetts, which was
completed in 1965. State Street leases approximately 500,000 square feet (or
approximately 54% of the space in this building). The initial lease term was 30
years with two successive extension options of 20 years each at negotiated
rental rates. State Street exercised the first of these two options, which
became effective on January 1, 1996 for a term of 20 years.


State Street owns five buildings located in Quincy, Massachusetts, a city south
of Boston. Four of the buildings, containing a total of approximately 1,365,000
square feet, function as State Street Bank's operations facilities. The fifth
building, with 186,000 square feet, is leased to Boston Financial Data Services,

Item 5. Market for Registrant's Common Equity and Related Stockholder Matters


Information concerning the market prices of and dividends on State Street's
common stock during the past two years appears on page 27 of State Street's 1998
Annual Report to Stockholders and is incorporated by reference. There were 6,457
stockholders of record at December 31, 1998. State Street's common stock is
listed on the New York Stock Exchange, ticker symbol: STT. State Street's common
stock is also listed on the Boston and Pacific Stock Exchanges.


On May 28, 1997, State Street distributed a two-for-one stock split in the form
of a 100% stock dividend to shareholders.


Directors who are also employees of the Corporation or the Bank receive no
compensation for serving as directors or as members of committees. Directors who
are not employees of the Corporation or the Bank received an annual retainer of
$35,000, payable at their election in shares of Common Stock of the Corporation
or in cash, and an award of 251 shares of deferred stock payable when the
director leaves the Board or retires, for the period April 1998 through March
1999. In 1998, all outside directors elected to receive their annual retainer in
shares of Common Stock. On July 1, 1998, two of the Directors, who joined the
Board in September 1997, each received a prorated award of 137 deferred shares
for the 1997-1998 period. An aggregate of 7,648 shares were issued as retainers,
and rights to receive an aggregate of 4,290 deferred shares were awarded, in
1998. Exemption from registration of the shares is claimed by the Corporation
under Section 4(2) of the Securities Act of 1933.


Under a plan effective January 1, 1995, non-employee directors with at least
five years of service were eligible for an annual retirement benefit equal to
their annual retainer at retirement, payable for a period equal to the length of
service of the director on the Board, up to a maximum of ten years. On March 19,
1998, the Directors' Retirement Plan was terminated, and Directors with five or
more years of service with the Corporation were allowed to maintain their
accrued benefits pursuant to the Plan or to transfer the value of the accrued
benefits into a deferred stock account. Directors with less than five years of
service had their benefits automatically transferred into a deferred stock
account. One of the Directors elected to maintain his accrued benefits pursuant
to the Plan. Rights to receive an aggregate of 23,527 deferred shares were
awarded for this transfer. Future accruals under the Directors' Retirement Plan
have been replaced with annual deferred stock awards equal, in each case, to the
number of shares of the Common Stock of the Corporation determined by dividing
$7,000 by the current share price. Rights to receive an aggregate of 1,612
deferred shares were awarded for the period April 1998 through March 1999.
Exemption from registration of the shares is claimed by the Corporation under
Section 4(2) of the Securities Act of 1933.

DESCRIPTION OF 1998 DEFERRED STOCK AWARDS TO NON-EMPLOYEE
DIRECTORS

     Under a plan effective January 1, 1995, non-employee directors with at
least five years of service were eligible for an annual retirement benefit equal
to their annual retainer at retirement, payable for a period equal to the length
of service of the director on the Board, up to a maximum of ten years. On March
19, 1998, by vote of the Board of Directors, the Directors' Retirement Plan was
terminated, and Directors with five or more years of service with the
Corporation were allowed to maintain their accrued benefits pursuant to the plan
or to transfer the value of the accrued benefits into a deferred stock account.
Directors with less than five years of service had their benefits automatically
transferred into a deferred stock account. Rights to receive an aggregate of
23,527 deferred shares were awarded for this transfer. One of the Directors
elected to maintain his accrued benefits pursuant to the plan. Future accruals
under the Directors' Retirement Plan have been replaced with annual deferred
stock awards equal, in each case, to the number of shares of the Common Stock of
the Corporation determined by dividing $7,000 by the current share price. Rights
to receive an aggregate of 1,612 deferred shares were awarded for the period
April 1998 through March 1999.

     DESCRIPTION OF 1998 STOCK ISSUANCES IN LIEU OF CASH RETAINER FOR
NON-EMPLOYEE DIRECTORS

     For the period April 1998 through March 1999, directors who are not
employees of the Corporation or the Bank received an annual retainer of $35,000,
payable at their election in shares of Common Stock of the Corporation or in
cash, and, by vote of the Board of Directors, an award of 251 shares of deferred
stock payable when the director leaves the Board or retires (or, if so elected
by an individual director, on a later date, but not more than 10 years after the
individual ceases to be a director). In 1998, all outside directors elected to
receive their annual retainer in shares of Common Stock, In July 1998, two of
the Directors, who joined the Board

<PAGE>

in September 1997, each received a prorated award of 137 deferred shares for the
1997-1998 period. An aggregate of 7,648 shares were issued as retainers, and
rights to receive an aggregate of 4,290 deferred shares were awarded, in 1998.

     The deferred shares so awarded are subject to adjustment in the event of a
capitalization change at State Street, and are credited with notional dividends.
The terms of the award are administered by the Board of Directors, which may, at
any time, vote to accelerate the issuance of the deferred shares to a director.

FINANCIAL REVIEW
- --------------------------------------------------------------------------------
This section provides management's discussion and analysis of State Street's
consolidated results of operation for the three years ended December 31, 1998,
and its financial condition at year-end 1998. It should be read in conjunction
with the Consolidated Financial Statements and Supplemental Financial Data.

State Street is a leading specialist in serving institutional investors
worldwide. Among the services State Street provides customers are:

[bullet]  Custody, accounting, daily pricing and administration
[bullet]  Foreign exchange, cash management and securities lending
[bullet]  Investment management
[bullet]  Information and trading
[bullet]  Banking services

RESULTS OF OPERATIONS
- --------------------------------------------------------------------------------

SUMMARY
- --------------------------------------------------------------------------------
In 1998, State Street's earnings per diluted share were $2.66, up 15% from the
outstanding performance of 1997. Total revenue of $2.8 billion increased 18%
from the previous year. Revenue growth was driven by growth in fiduciary
compensation, net interest revenue and foreign exchange revenue. Net income was
$436 million, up 15%. Return on stockholders' equity was 20.2%. With these
strong results, the Corporation performed well against its financial goals.

State Street's primary financial goal is to achieve sustainable real
(inflation-adjusted) growth in earnings per share. Over the last 15 years,
earnings per diluted share increased at a 16% compound annual growth rate. State
Street's two supporting financial goals are related to revenue growth and return
on stockholders' equity. The revenue goal, to repeat the strong revenue growth
of the 1980s in the 1990s, requires 12.5% real (inflation-adjusted) growth, or
approximately a 15% nominal compound annual growth rate. For the decade to date,
nominal revenue has increased at a 17% compound annual growth rate. Return on
stockholders' equity was 20.2% for 1998, exceeding State Street's goal of 18%.

This was State Street's twenty-first consecutive year of double-digit earnings
per share growth. State Street's consistent financial performance demonstrates
successful execution of its strategic plan to build value for its stockholders,
in part by continuing to invest in technology, new products and services, and
expansion into new markets.

Growth in revenue is integral to State Street's consistent financial
performance. In 1998, approximately 80% of State Street's increase in revenue
came from existing customers, and the remaining 20% came from new customers.
Revenue growth was driven by customers' expanding needs, arising in part from
the continuation of long-term, global trends: aging of the world's population,
pressures on pay-as-you-go pension systems, increasing cross-border investing,
and the growing complexity of investment strategies. Management has positioned
State Street to benefit from these trends.

Some environmental factors favorably affected State Street's performance in
1998. Securities values were generally higher than in 1997. Currency markets
were active and volatile. U.S. mutual funds experienced continued strong cash
inflows.

State Street achieved strong sales success in 1998. Given the level of new
business signed and the continuation of the long-term trends driving demand for
the services State Street provides, management is optimistic about State
Street's long-term prospects. Management remains confident that execution of its
strategic business plan will continue to create value for stockholders.

varied and complex needs. Customers continue to increase the number of State
Street products they use. The Corporation's 1,000 largest customers used an
average of 5.8 products in 1998, up from 5.5 in 1997.

State Street classifies revenue received for services as either fee revenue or
net interest revenue, according to the service provided. Management focuses on
increasing total revenue. In 1998, total revenue grew 18%, to $2.8 billion.

FEE REVENUE

In 1998, fee revenue, which accounted for 72% of total revenue, was $2.0
billion, up $324 million, or 19%, from 1997 due to new business both from
existing customers and new customers, and due to customer growth.

Fee revenue growth came from fiduciary compensation, up $252 million; foreign
exchange trading revenue, up $44 million; and servicing and processing fees, up
$18 million.

</TABLE>

Fiduciary Compensation

Fiduciary compensation, up 20% in 1998, is the largest component of fee revenue.
Fiduciary compensation is derived from accounting, custody, daily pricing,
information services, securities lending, trusteeship services and investment
management.

Fees recorded in fiduciary compensation are a function of the mix and volume of
assets under custody and assets under management, securities positions held,
portfolio transactions, and securities on loan. If equity values worldwide were
to increase or decrease 10%, State Street estimates that this, by itself, would
cause approximately a 2% change in total revenue. If bond values were to change
by 10%, State Street would anticipate less than a 1% change in total revenue.

The following sections discuss the factors contributing to growth in fiduciary
compensation, presented by market segment. State Street's customers use other
complementary services that are recorded in other revenue categories, such as
foreign exchange trading revenue and net interest revenue.

Services for Institutional Investors. In 1998, fiduciary compensation for
Services for Institutional Investors was $1.0 billion, up 19% from 1997.
Services for Institutional Investors revenue increasingly reflects customers'
use of services other than basic custody, such as mutual fund accounting and
administration, services for offshore mutual funds, securities lending,
performance and analytics, and compliance monitoring.

Mutual Funds. State Street is the largest mutual fund custodian and accounting
agent in the United States. State Street provides custody services for 42% of
registered U.S. mutual funds. State Street is distinct from many other mutual
fund service providers because customers make extensive use of a number of
related services in addition to custody, including accounting and daily pricing.
The Corporation provides fund accounting and valuation services for more than
five times the assets serviced by the next largest accounting service provider.
State Street is responsible for calculating 27% of the U.S. mutual fund prices
that appear daily in The Wall Street Journal. Services such as fund accounting
and administration, accounting for multiple classes of shares, master/feeder
accounting, and services for offshore funds and local funds in locations outside
the United States contribute to fiduciary compensation. Shareholder services are
provided through an affiliate, Boston Financial Data Services, Inc.

A long-term revenue driver is the number of mutual fund complexes, or mutual
fund families, the Corporation services. Once a mutual fund complex becomes a
customer, that complex is likely to select State Street to provide more
services, service more funds, or both. In addition, State Street benefits from
the growth of its customers. At year-end 1998, 253 mutual fund complexes used
State Street's services, up from 247 a year ago.

In 1998, revenue growth from servicing mutual funds came primarily from new
business, both from existing customers and new customers. Increased revenue from
accounting and custody reflected growth in assets and additional mutual funds.
Revenue from servicing offshore funds and from mutual fund administration
continued to increase.

In 1998, total mutual fund assets under custody increased 26%. The total number
of funds serviced increased by 340, or 10%, to 3,661. There were 583 new funds
serviced, 500 from existing customers and 83 from new customers, partially
offset by 243 funds no longer serviced due primarily to mergers and
consolidations of funds. The number of offshore funds serviced was up 14% from a
year ago and offshore assets increased 41%. Assets under administration were up
21%.

U.S. Pension, Insurance and Other Investment Pools. State Street provides
custody, portfolio accounting, securities lending, information and other related
services for retirement plans and other financial asset portfolios of
corporations, public funds, investment managers, non-profit organizations,
unions and others. The Corporation provides products and services, such as
performance and analytics, global reporting, and compliance monitoring, that
these institutional customers require to meet their changing needs. In 1998,
revenue growth was driven by new business and securities lending.

State Street has a leading share of the market for servicing U.S. tax-exempt
assets for corporate and public pension funds. Over the past five years, State
Street's market share has grown from 17% to 24%.

Customers Outside the United States. State Street is committed to expanding
globally by serving the global needs of both its U.S. and non-U.S. domiciled
customers. Revenue growth in 1998 from customers outside the United States was
driven primarily by new business, including business gained by an acquisition.
In 1998, assets under custody for these customers totaled $362 billion, an
increase of 36% from 1997, with strong growth in Europe, Canada and Japan. Over
the last five years, assets under custody for these customers have increased at
a compound annual growth rate of 32%.

Investment Management. Fiduciary compensation for Investment Management was $480
million, up 23% from 1997.

State Street provides an extensive range of investment management services,
including investment management for corporations, public funds and other
institutional investors; administration and investment services for defined
contribution and other employee benefit programs; and investment management and
other financial services for high-net-worth individuals. These services are
offered through State Street Global Advisors ("SSgA[RegTM]"). In the United
States, SSgA is the largest manager of tax-exempt assets, the third-largest
manager of defined contribution plan assets and the third-largest manager of
total assets. Globally, SSgA is the seventh-largest manager of total assets.

SSgA offers a broad array of investment strategies, including passive, enhanced
and active management using quantitative and fundamental methods for both global
equities and global fixed income. Fees are based

In 1998, the increase in revenue from investment management for institutional
investors reflected new business installed, additional contributions from
existing customers and higher values of U.S. equities. Revenue growth was driven
principally by customers' use of passive equity strategies and fixed income
strategies, including short-term investments.

Revenue from providing participant services to defined contribution and other
employee benefit programs grew as a result of an acquisition, new business and
growth in existing business. The number of defined contribution plan
participants served increased to 2.6 million from 2.4 million in 1997.

Assets Under Custody and Management. The amounts of assets under custody and
management indicate the relative size of various markets served and, as adjusted
for market-value changes, serve as proxies for business growth. However, changes
in asset levels do not necessarily result in proportional changes in revenue,
due to the many services that are priced on factors other than asset size and
State Street's relationship pricing for customers who use multiple services.

Market value changes had a positive impact on the value of assets under custody
in 1998. The U.S. equity market, as measured by the total return of the S&P 500
index, increased 29%, while the broader market, as measured by the Wilshire
5000, increased 23%. U.S. bond markets, as measured by the Lehman Brothers
Aggregate Bond index, increased 9%. International equity markets, as measured in
U.S. dollars by the Morgan Stanley EAFE index, increased 20%.

At year-end 1998, total assets under custody increased $909 billion, or 23%, to
$4.8 trillion, from 1997.

FINANCIAL REVIEW
- --------------------------------------------------------------------------------

Approximately 55% of these assets under custody were equities, 27% were fixed
income instruments, and 18% were short-term instruments. Non-U.S. securities
comprised 12% of total assets under custody, with emerging markets securities
comprising less than 1%.

At year-end 1998, assets under management increased $95 billion to $485 billion,
or 24%, from 1997. Non-U.S. securities comprised 21% of total securities, with
emerging markets securities comprising 1%.

Foreign Exchange Trading

In 1998, foreign exchange trading revenue rose 18%, to $289 million. Major
currencies were slightly more volatile than in 1997. Currency volatility in both
1998 and 1997 was significantly greater than in 1996. The dollar volume of
customer trades was up 29% from 1997.

Development of a comprehensive range of foreign exchange services to meet the
needs of institutional investors helped State Street earn the number two ranking
for "Best FX Service Overall" in a 1998 worldwide survey of global foreign
exchange providers conducted by Global Investor magazine.

In 1998, the number of investment managers using State Street's foreign exchange
services increased to 698, from 625 a year ago, and many existing relationships
expanded. A contributor to new foreign exchange business is State Street Global
Link,(SM) an integrated, electronic platform that includes unique research and
trade execution capabilities.

Servicing and Processing

Servicing and processing revenue includes fees from brokerage services, software
licensing and maintenance, loans, investment banking, and trade banking.
Servicing and processing revenue of $177 million was up 12% from 1997. Fees from
brokerage services and investment banking products drove revenue growth.
Servicing and processing revenue in 1997 included revenue from a non-strategic
business sold in June of that year.

Other Fee Revenue

Other fee revenue includes gains and losses on sales of investment securities,
leased equipment, and other assets; gains and losses on currency translation;
trading account profits and losses; profit or loss from joint ventures; and
amortization of investments in tax-advantaged financings. In 1998, other fee
revenue grew $10 million, principally due to gains on sales of investment
securities.

NET INTEREST REVENUE

Net interest revenue is the amount of interest received on interest-earning
assets less the interest paid on interest-bearing liabilities. In this
discussion, net interest revenue is expressed on a fully taxable-equivalent
basis to adjust for the tax-exempt status of revenue earned on certain
investment securities and loans.

</TABLE>

Taxable-equivalent net interest revenue in 1998 was $785 million, up $100
million, or 15%, over 1997. This growth was primarily due to an increase in
customer liabilities.

In serving institutional investors worldwide, State Street provides short-term
funds management, deposit services and repurchase agreements for cash positions
associated with customers' investment activities. The revenue associated with
deposit services and repurchase agreements, as well as from lending and lease
financing activities, is recorded as net interest revenue.

In 1998, State Street continued to expand globally, installing new customers and
benefiting from existing customers' growth, activity, and use of additional
services. These customers, in conjunction with their world-wide investment
activities, increased their level of deposits and securities sold under
repurchase agreements.

Customer funds from these sources increased $8.8 billion and funded most of the
growth in average interest-earning assets, which increased $10.0 billion, or
32%, to $41.4 billion. Loans increased $996 million, or 19%, from last year, due
to growth in commercial loans, securities settlement advances and lease
financing.

Net interest margin, which is defined as taxable-equivalent net interest revenue
as a percent of average interest-earning assets, declined from 2.18% in 1997 to
1.90% in 1998, due to balance sheet growth in short-term money market
instruments and a flatter U.S. yield curve.

OPERATING EXPENSES
- --------------------------------------------------------------------------------
In 1998, operating expenses were $2.1 billion, up 19% from 1997. Expenses
increased as a result of investments for future growth, particularly people and
technology to support business volumes, product-line expansion through
development and acquisition, non-U.S. expansion, Year 2000 preparations, the
euro conversion, and other strategic business initiatives.

Installation of new business and existing customers' growth resulted in greater
business volume. Total assets under custody increased 23% and the volume of
securities transactions was up 16%. Assets under management were up 24%.

</TABLE>

Salaries and employee benefits, the largest component of expense, was $1.2
billion, up 21% from 1997 due to additional staff supporting business growth.
The total number of employees at year end was 16,816, an increase of 18% from
year-end 1997. Approximately one-fourth of the staff growth was due to
acquisitions and the transfer of staff from a customer that outsourced
accounting and administration services to State Street.

Information systems and communications expense was $241 million, up 30%,
reflecting expansion of business capacity through information technology,
including processing and storage capacity, servers, and software. These
resources are necessary to support the increased volume and complexity of
business serviced, global expansion, and introduction of new products and
services. Transaction processing services are volume-related and include
external contract services, subcustodian fees and fees related to securities
settlement. This expense category was $196 million, up 7%.

Occupancy expense increased 25%, to $164 million, primarily due to growth in
existing locations and new space to support geographic expansion.

Other expenses include professional services, advertising, sales promotion and
other expenses. In 1998, other expenses were $292 million, up 12%, due to
increased use of professional services, including outsourced software
development, and advertising and sales promotion.


INCOME TAXES
- --------------------------------------------------------------------------------
Income tax expense was $221 million in 1998, compared to $184 million in 1997.
In 1998, the effective tax rate was 33.6%, up from 32.6% in 1997. The higher
effective tax rate for 1998 was primarily attributable to the increase in fully
taxable income, which was partially offset by higher tax credits and other
initiatives to minimize income tax expense worldwide.

ACQUISITIONS, ALLIANCES
AND DIVESTITURE
- --------------------------------------------------------------------------------
State Street makes acquisitions for strategic purposes. Acquisitions and
alliances enhance established capabilities by adding new products or services,
expanding geographic reach, or selectively expanding market share. State Street
is actively involved in reviewing and assessing various business opportunities
related to this strategy. In addition, State Street continuously reviews current
business operations to determine the applicability of these businesses to State
Street's core mission.

During 1998, State Street completed several acquisitions and alliances.

In February, State Street completed the acquisition of Bank of Scotland's unit
trust trustee business in the United Kingdom. This business complements State
Street's established expertise in accounting and fund administration, providing
a foundation on which State Street is building a full-service trustee,
accounting, and

fund administration operation for the United Kingdom's collective investment
fund market.

In April, State Street acquired the remaining 50% partnership interest in
Wellspring Resources LLC, a provider of total benefits outsourcing.

State Street established several strategic alliances in 1998. These included
alliances with Nedcor Bank Limited, to meet the global and domestic service
requirements of institutional investors in South Africa, and Italy's Mediolanum,
an insurance and mutual fund group, to form a joint venture targeting defined
contribution-type pension plans.

In addition, in December, the Corporation sold a non-strategic business
servicing unclaimed property.

YEAR-2000 READINESS DISCLOSURE
- --------------------------------------------------------------------------------

Resolution 2000 Program Scope and Oversight. The approaching Year 2000 presents
companies in all industries with many challenges to ensure Year-2000 readiness
of their computer systems and processes. These challenges stem from a
once-common programming standard using two-digit years for date fields contained
in computer programs and related data. Commencing in 1996, State Street assessed
the impact of the upcoming Year 2000 on its operations and developed a
comprehensive program, Resolution 2000, to address the related issues.

This program covers six major areas of Year-2000 readiness: information
technology infrastructure, global data networks, core application software,
business area supported applications, facilities and third-party suppliers.
Information technology infrastructure, global data networks and core application
software make up what is commonly referred to as information technology ("IT")
systems. More specifically, information technology infrastructure is the
hardware and system software required to support the core application software,
which consists of State Street's custody, accounting, deposits, loans, cash
management and investment management systems. Global data networks consist of
the wide and local area networks and telephone/PBX systems. Business area
supported applications are those desktop applications developed and supported by
non-IT areas, and include office equipment such as fax machines. Facilities is
the embedded technology used throughout State Street's offices; for example, in
the uninterrupted power supply, fire alarms, security, and heating and
air-conditioning systems. Third-party suppliers refers to all external parties,
including vendors, service providers, subcustodian banks, counterparties,
business partners and customers, that have the potential to affect State
Street's ability to deliver Year-2000 ready products and services.

State Street engaged a consulting firm at the onset of the Resolution 2000
program to assist in the area of program management, and to provide professional
technical resources to the program as required. This firm was selected for its
recognized leadership in management of large-scale information technology
programs and for its established methodology. This methodology forms the basis
for State Street's activities, in conjunction with its consultant, in applying
the Resolution 2000 program to the core application software area. Using this
methodology, there is a phased approach followed that includes identifying and
validating an inventory of potentially date-sensitive items; assigning a
business risk rating to each item; assessing the Year-2000 readiness status of
each item; taking corrective action to renovate, replace, retire, upgrade or
outsource to achieve Year-2000 readiness; validating Year-2000 readiness through
several levels of testing (regression, internal and external Year-2000 testing);
and developing and validating business-resumption contingency plans for each
critical business function as required. The methodology and phased approach are
being applied to all other areas of the Resolution 2000 program in performing
similar activities.

A central program management office, global Year-2000 readiness teams and a
corporate oversight structure support the Resolution 2000 program. Program
updates, progress reports and critical matters are regularly communicated to
senior management and to the Board of Directors.

The Resolution 2000 program activities are incorporated into State Street's
corporate risk-management functions. In addition, these program activities are
subject to reviews, which include internal audits and regulatory examinations
performed by the Federal Reserve Bank.

State Street has delayed certain IT projects unrelated to Year-2000 readiness
due to resources committed to the Resolution 2000 program. The impact of these
delays is not expected to have a material adverse impact on State Street's
financial condition or results from operations.

State of Readiness. At December 31, 1998, State Street had completed the
inventory, risk assessments and Year-2000 readiness assessment work. Both
implementation of corrective actions required to achieve Year-2000 readiness,
and regression and internal testing to validate Year-2000 readiness, were
nearing completion. External testing with key industry organizations, such as
the Federal Reserve Bank, Depository Trust Corporation and Society for Worldwide
Inter-bank Financial Telecommunications (SWIFT), commenced in the third quarter
of 1998, with all tests to date successfully completed. External testing

State Street considers the IT infrastructure work remaining, consisting of
internal Year-2000 testing and production implementation of certain
third-party-provided system software products used in the client server
environments, to be mission critical. A portion of the core application software
work remaining, primarily the internal testing to validate the Year-2000
readiness, is also considered mission critical. State Street currently
anticipates that implementation of corrective actions required to achieve
Year-2000 readiness and internal testing to validate Year-2000 readiness will be
completed for internal mission-critical systems by March 31, 1999, with
remaining systems complete by June 30, 1999. External testing will be a focus in
the first half of 1999 and is expected to be completed in the third quarter of
1999. State Street's Year-2000 contingency planning program is underway,
leveraging the strength of State Street's business-resumption contingency plans.
Year-2000 contingency plan development is expected to be complete by the second
quarter of 1999. Validation of these plans is expected to be completed in the
third quarter of 1999.

Progress at December 31, 1998, related to third-party suppliers, the readiness
of which could affect State Street's ability to deliver Year-2000 ready products
and services, is as follows:

Internal communications with vendors to obtain information on the Year-2000
readiness status of the products and services provided to State Street has been
completed. State Street has substantially completed development of remediation
contingency plans for those products and services that are considered high-risk.
Key vendors were asked to present updates to State Street on their Year-2000
readiness programs and related progress. Year-2000 readiness assessments of key
vendors have been completed and the current and future focus has turned to
implementation of remediation and business-resumption contingency planning.


Year-2000 readiness has been incorporated into State Street's existing due
diligence procedures performed with business partners and counterparties.
Year-2000 assessments of business partners have been completed and the focus has
turned to implementation of remediation and business-resumption contingency
planning. Year-2000 counterparty assessments are substantially complete.

Year-2000 readiness has been incorporated into the existing due diligence
procedures for State Street's subcustodian bank network. In addition,
questionnaires have been sent to the subcustodians focusing on the adequacy of
their Year-2000 readiness programs and implementation plans, including testing
with State Street. Subcustodian contingency planning efforts aimed at
identifying alternative subcustodian banks in each of State Street's markets is
complete. Year-2000 readiness testing began with subcustodians in the fourth
quarter of 1998 and is anticipated to be completed in the third quarter of 1999.

Risks of Year-2000 Issues. State Street's businesses are substantially dependent
upon its data processing software and hardware systems, and upon its ability to
process information. If the Corporation failed to be Year-2000 ready, as
compared to its competitors, there could be an adverse effect on State Street's
business. In addition, since the Corporation and its subsidiaries are regulated
by federal, state and local banking authorities, and securities regulators,
failure to be Year-2000 compliant could subject State Street to formal
supervisory or enforcement actions, which could have an adverse impact on State
Street's business. State Street works with various third parties, including
customers, vendors and intermediaries. Failure of any key third party to be
Year-2000 ready could adversely affect State Street's business.

Contingency Plans. State Street cannot control the success of the Year-2000
readiness program of each third-party supplier. In instances where the risk of
Year-2000 readiness failure is high and there is potential for State Street not
providing or not receiving a compliant product, or if scheduled delivery is
beyond an acceptable date, the Corporation will adopt business-resumption
contingency plans. To mitigate the effects of its significant customers',
suppliers' or vendors' potential failure to remediate a Year-2000 issue in a
timely manner, State Street would take reasonable contingency actions. These may
include using alternative sources of supplies or services, manual workarounds,
or other event management. The ultimate goal in developing contingency plans is
to have an uninterrupted flow of information between State Street and
third-party providers in the Year 2000 and beyond. State Street expects to have
business contingency plans in place by the second quarter of 1999. If it becomes
necessary for

FINANCIAL REVIEW
- --------------------------------------------------------------------------------

State Street to take these corrective actions, it is uncertain, until the
contingency plans are implemented, whether this would result in significant
delays in business operations or have a material adverse effect on State Street.

Costs. Management currently estimates the aggregate cost of the Resolution 2000
program to be less than 2% of total operating expenses for the five-year period
1996-2000. As of December 31, 1998, cumulative program expenditures were $72
million, of which $49 million was incurred during 1998. Such costs are expensed
as incurred and include approximately 400 full-time staff and consultants,
equipment, and other expenses.

EUROPEAN ECONOMIC AND
MONETARY UNION
- --------------------------------------------------------------------------------
On January 1, 1999, eleven member countries participating in the European
Economic and Monetary Union (EMU) adopted a common currency, the euro, and
established fixed conversion rates between their existing sovereign currencies
and the euro. For three years the participating countries can perform financial
transactions in either the euro or their original local currencies, resulting in
a fixed exchange rate among the participating countries. State Street's
information systems and business operations have been modified to service
customer accounting and other needs resulting from this currency adoption. In
1996, State Street began preparations to modify its information systems and
business operations in order to implement conversion to the euro. The conversion
effort was a major corporate focus in 1998, involving a dedicated EMU project
management office and an executive steering group.

The costs associated with the implementation and redenomination to the euro are
not expected to be material. While the adoption of the euro is expected to
affect trading volumes and deposit account balances within Europe throughout
1999, and while it is anticipated that new opportunities may arise from the
monetary union, management does not expect the impact of the euro to have a
material effect on State Street's financial condition.

COMPARISON OF 1997 VERSUS 1996
- --------------------------------------------------------------------------------
In 1997, diluted earnings per share increased 30% to $2.32. Total revenue
increased 24% and return on stockholders' equity was 20.6%, up from 18.1% in
1996.

This strong performance exceeded all financial goals and historical trends.
Revenue grew in all businesses and was driven by new business worldwide,
including new relationships and existing customers' use of additional products
and services. A generally favorable business environment, including the
continued expansion of cross-border investing, contributed to revenue growth as
well.

LINES OF BUSINESS
- --------------------------------------------------------------------------------
State Street reports three lines of business: Services for Institutional
Investors, Investment Management and Commercial Lending. The operating results
of these lines of business are not necessarily comparable with other companies.

Revenue and expenses are directly charged or allocated to the lines of business
through algorithm-based management information systems. State Street prices on
total customer relationships and other factors; therefore, revenues may not
necessarily reflect market pricing on products within the business lines in the
same way as they would for separate legal entities. Assets and liabilities are
allocated according to rules that support management's strategic and tactical
goals. Capital is allocated based on risk-weighted assets employed and
management's judgment. The capital allocations may not be representative of the
capital that might be required if these lines of business were independent
business entities.

In the following table, certain previously reported line of business information
has been restated to conform to the current method of presentation.

SERVICES FOR
INSTITUTIONAL INVESTORS

Services for Institutional Investors includes accounting, custody, daily pricing
and information services for investment portfolios. Customers around the world
include mutual funds and other collective investment funds, corporate and public
pension plans, corporations, investment managers, non-profit organizations,
unions, and other holders of investment assets. Institutional investors are
offered State Street services, including foreign exchange, cash management,
securities lending, fund administration, recordkeeping, banking services, and
deposit and short-term investment facilities. These services support
institutional investors in developing and executing their strategies, enhancing
their returns, and evaluating and managing risk. Revenue from this line of
business comprised 71% of State Street's total revenue for 1998.

Revenue increased to $2.0 billion, up 16% from $1.7 billion in 1997. The $278
million increase in revenue was driven by expanding relationships with customers
who are growing and using more services, the installation of new business, and
higher equity values.

Fee revenue was up $212 million, or 18%, due to growth in fiduciary compensation
and foreign exchange trading revenue. Fiduciary compensation, up 19%, reflected
substantial revenue increases from accounting, custody and other services for
mutual funds, U.S. pension plans and customers outside the United States.
Foreign exchange trading revenue grew 18% from a year ago due to growth in the
volume of customer trades, the level of currency volatility and the increased
use of State Street Global Link.

Net interest revenue, up 14%, reflected the results of investing customer
deposits and other short-term funds in interest-earning assets. In 1998,
customer funds, including non-U.S. deposits, repurchase agreements and
noninterest-bearing deposits, grew substantially.

Operating expenses were $1.5 billion, 16% higher than in 1997, supporting
business growth, investments for future growth and acquisitions.

In 1998, income before income taxes was $470 million, an increase of $68
million, or 17%, from 1997. The pre-tax margin was 24%.

INVESTMENT MANAGEMENT

State Street manages financial assets worldwide for both institutions and
individuals and provides related services, including participant services for
defined contribution and other employee benefit programs, and brokerage
services. Investment management offers a broad array of services, including
passive and active equity, money market, and fixed income strategies. Revenue
from this line of business comprised 20% of State Street's total revenue for
1998.

Revenue grew 26%, to $558 million, due to growth across all businesses.

Operating expenses increased $114 million, or 33%, to $461 million, reflecting
investment in additional staff, systems and office space to expand the product
line and broaden State Street's global reach; and the acquisition of the
remaining 50% partnership interest in Wellspring Resources LLC.

In 1998, income before income taxes was $97 million, an increase of $2 million,
or 2%, from 1997. Pre-tax margin was 17%.

COMMERCIAL LENDING

Reported in this line of business are lending activities and other banking
services for regional middle-market companies, companies in selected industries
and institutional investor customers. Other banking services include cash
management and deposit services. Revenue from this line of business comprised 9%
of State Street's total revenue for 1998.

Revenue grew to $234 million, up 15%, from $204 million in 1997, due primarily
to increased loans and leases, and increased fee revenue. Lease financing,
international trade finance, and loans to businesses in the northeastern United
States and specialty industries nationwide all grew. Increased revenue came from
gains on the sale of leased equipment and lending activity.

In 1998, credit quality remained strong. The provision for loan losses was $17
million, up from $16 million a year ago, supporting growth in loans outstanding.
The provision for loan losses and the credit experience of State Street for the
three years ended December 31, 1998 is shown in Note D to the Consolidated
Financial Statements on page 36.

Operating expenses increased $11 million, or 12%, to $104 million.

In 1998, income before income taxes was $130 million, an increase of $19
million, or 17%, from 1997. Pre-tax margin was 56%.

FINANCIAL REVIEW
- --------------------------------------------------------------------------------

FINANCIAL GOALS AND FACTORS
THAT MAY AFFECT THEM
- --------------------------------------------------------------------------------
State Street's primary financial goal is sustainable real growth in earnings per
share. The Corporation has two supporting goals, one for total revenue growth
and one for return on common stockholders' equity (ROE). The revenue goal is a
12.5% real, or inflation-adjusted, compound annual growth rate of revenue for
the decade of the 1990s. This translates to approximately a 15% nominal compound
annual growth rate. The ROE goal is 18%.

State Street considers these to be financial goals, not projections or
forward-looking statements. However, the discussion in this Financial Review,
and in other portions of this Annual Report, does contain statements that are
considered "forward-looking statements" within the meaning of the federal
securities laws. These statements may be identified by such forward-looking
terminology as "expect," "look," "believe," "anticipate," "may," "will," or
similar statements or variations of such terms. The Corporation's financial
goals and such forward-looking statements involve certain risks and
uncertainties, including the issues and factors listed below and factors further
described in conjunction with the forward-looking information, which could cause
actual results to differ materially. The following issues and factors should be
carefully considered. The Corporation assumes no obligation for updating any
such forward-looking information.

Based on evaluation of the following factors, management is currently optimistic
about the Corporation's long-term prospects.

Cross-border investing. Increases in cross-border investing by customers
worldwide benefit State Street's revenue. Future revenue may increase or
decrease depending upon the extent of increases or decreases in cross-border
investments made by customers or future customers.

Savings rate of individuals. State Street benefits from the savings of
individuals that are invested in mutual funds or in defined contribution plans.
Changes in savings rates or investment styles may affect revenue.

Value of worldwide financial markets. As worldwide financial markets increase or
decrease in value, State Street's opportunities to invest and service financial
assets may change. Since a portion of the Corporation's fees are based on the
value of assets under custody and management, fluctuations in worldwide
securities market valuations will affect revenue, as discussed on page 15.

Dynamics of markets served. Changes in markets served, including the growth rate
of U.S. mutual funds, the pace of debt issuance, outsourcing decisions, and
mergers, acquisitions and consolidations among customers and competitors, can
affect revenue. In general, State Street benefits from an increase in the volume
of financial market transactions serviced.

State Street provides services worldwide. Global and regional economic factors
and changes or potential changes in laws and regulations affecting the
Corporation's business, including volatile currencies and changes in monetary
policy, and social and political instability, could affect results of
operations.

Interest rates. Market interest rate levels, the shape of the yield curve and
the direction of interest rate changes affect net interest revenue as well as
fiduciary compensation from securities lending. All else being equal, in the
short term, State Street's net interest revenue benefits from falling interest
rates and is negatively affected by rising rates because interest-bearing
liabilities reprice sooner than interest-earning assets.

Volatility of currency markets. The degree of volatility in foreign exchange
rates can affect the amount of foreign exchange trading revenue. In general,
State Street benefits from currency volatility.

Pace of pension reform. State Street expects to benefit from worldwide pension
reform that creates additional pools of assets that use custody and related
services and investment management services. The pace of pension reform may
affect the pace of revenue growth.

Pricing/competition. Future prices the Corporation is able to obtain for its
products may increase or decrease from current levels depending upon demand for
its products, its competitors' activities and the introduction of new products
into the marketplace.

Pace of new business. The pace at which existing and new customers use
additional services and assign additional assets to State Street for management
or custody will affect future results. State Street believes that uncertainties
resulting from the Year 2000 issues could have an impact on new business for
1999 such that customers and potential customers of State Street will be less
inclined in the second half of 1999 to consider changing their business
relationships.

Business mix. Changes in business mix, including the mix of U.S. and non-U.S.
business, may affect future results.

Rate of technological change. Technological change creates opportunities for
product differentiation and reduced costs, as well as the possibility of
increased expenses. State Street's financial performance depends in part on its
ability to develop and market new and innovative services and to adopt or
develop new technologies that differentiate State Street's products or provide
cost efficiencies.

There are risks inherent in this process. These include rapid technological
change in the industry, the Corporation's ability to access technical and other
information from customers, and the significant and ongoing investments required
to bring new services to market in a timely fashion at competitive prices.
Further, there is risk that competitors may introduce services that could
replace or provide lower-cost alternatives to State Street's services.

<PAGE>

State Street uses appropriate trademark, trade secret, copyright and other
proprietary rights procedures to protect its technology, and has applied for a
limited number of patents in connection with certain software programs. The
Corporation believes that patent protection is not a significant competitive
factor and that State Street's success depends primarily upon the technical
expertise and creative abilities of its employees and the ability of the
Corporation to continue to develop, enhance and market its innovative business
processes and systems. However, in the event a third-party asserts a claim of
infringement of its proprietary rights, obtained through patents or otherwise,
against the Corporation, State Street may be required to spend significant
resources to defend against such claims, develop a non-infringing program or
process, or obtain a license to the infringed process.

Year-2000 modifications. The costs and projected completion dates for State
Street's Year-2000 program are estimates. Factors that may cause material
differences include the availability and cost of systems and other personnel,
non-compliance of third-party providers, and similar uncertainties. If necessary
modifications and conversions are not completed in time, the Year-2000 issue
could affect State Street's performance.

Acquisitions and alliances. Acquisitions of complementary businesses and
technologies, and development of strategic alliances are an active part of State
Street's overall business strategy, and the Corporation has completed several
acquisitions and alliances in recent years. However, there can be no assurance
that services, technologies, key personnel and businesses of acquired companies
will be effectively assimilated into State Street's business or service
offerings or that alliances will be successful.

European Economic and Monetary Union. The move to a common currency could affect
foreign exchange volumes and the level of deposits denominated in the euro or
the legacy currencies.

- --------------------------------------------------------------------------------

BALANCE SHEET
- --------------------------------------------------------------------------------
State Street provides deposit and other balance sheet services to its customers,
who are primarily institutional investors. These customers, in executing their
worldwide investment activities, require short-term investment vehicles and
deposit accounts. These short-term deposits and other customer funds comprise
the majority of State Street's liabilities. State Street's business mix results
in a distinctive composition of its balance sheet, which affects the
Corporation's approach to managing interest rate sensitivity, liquidity and
credit risk.

[pie chart ends]

LIABILITIES

The growth in State Street's balance sheet is primarily driven by growth in
liabilities. State Street uses its excess balance sheet capacity to support
customers' transactions and short-term investment strategies. State Street's
objectives and customers' needs determine the volume, mix and currencies of the
liabilities.

Average interest-bearing liabilities increased $8.7 billion, or 33%, in 1998.
The most significant growth in liabilities occurred in securities sold under
repurchase agreements, used primarily by mutual fund customers; and in non-U.S.
time, call and transaction deposits, used by both non-U.S. and U.S. customers.
Non-U.S. deposits grew 29%, to $16.3 billion; 38% of this balance consists of
transaction account balances, which have lower interest rates than other
interest-bearing sources of funds. Securities sold under repurchase agreements
increased 44%, to an average of $13.8 billion for the year. Long-term debt
increased, reflecting the issuance in May 1998 of $150 million of floating-rate
capital securities to provide cost-effective funding for corporate growth.

Noninterest-bearing deposits grew $966 million, or 18%. Customers use
noninterest-bearing deposit accounts for transaction settlements and to
compensate State Street for services.

ASSETS

State Street's assets consist primarily of short-term money market assets and
investment securities, which are generally more marketable than other types of
assets. Investment securities, principally classified as available-for-sale,
primarily include U.S. Treasury and Agency securities, highly-rated municipal
securities, asset-backed securities, and non-U.S. government bonds.
Interest-bearing deposits with banks are short-term, multi-currency instruments
invested with major U.S. and non-U.S. banks.

Average interest-earning assets increased $10 billion, or 32%, in 1998.
Securities purchased under resale agreement grew $6.5 billion, or 100%, from
1997. Additional

FINANCIAL REVIEW

customer funds, as well as maturing funds from the investment portfolio, were
primarily placed in short-term money market instruments due to the compression
of market spreads as the U.S. Treasury yield curve continued to flatten during
the year. Total investment securities fell $403 million, or 4%, from 1997.
Interest-bearing deposits with banks increased 32% from 1997, to $11.3 billion.
Total loans and leases increased 19%, to $6.3 billion.

During 1998, the loan portfolio, consisting of commercial loans, securities
settlement advances and lease financing, comprised 14% of State Street's assets.
This was down from 15% in 1997. Approximately one-third of the loan portfolio
supports the liquidity needs of institutional investors in their investing and
settlement activity.

FAIR VALUE OF
FINANCIAL INSTRUMENTS

The short-maturity structure of State Street's assets and liabilities results in
the fair value of its financial instruments equating to or closely approximating
their balance sheet value. See Note U to the Consolidated Financial Statements,
page 45, for further discussion.

FURTHER INFORMATION

Further quantitative information on State Street's assets and liabilities is
furnished in the Supplemental Financial Data on pages 50-51 and Notes C-H to the
Consolidated Financial Statements, pages 36-38.

LIQUIDITY AND CAPITAL
- --------------------------------------------------------------------------------

LIQUIDITY

The primary objective of State Street's liquidity management is to ensure that
the Corporation has sufficient funds to meet its commitments and business needs,
including accommodating the transaction and cash management requirements of its
customers. Liquidity is provided by State Street's access to global debt
markets, its ability to gather additional deposits from its customers, maturing
short-term assets, the sale of securities and payment of loans. Customer
deposits and other funds provide a multi-currency, geographically diverse source
of liquidity.

State Street maintains a large portfolio of liquid assets. When liquidity is
measured by the ratio of liquid assets to total assets, State Street ranks among
the highest 10% of U.S. bank holding companies. At December 31, 1998, the
Corporation's liquid assets were 80% of total assets.

State Street endeavors to maintain high ratings on its debt, as measured by
independent credit rating agencies. This ensures minimum borrowing costs and
enhances State Street's liquidity by ensuring the largest possible market for
the Corporation's debt. State Street's senior debt is rated AA- by Standard &
Poor's, A1 by Moody's Investors Service and AA by Fitch IBCA. State Street
Bank's long-term certificate of deposit ratings are AA by Standard & Poor's, Aa2
by Moody's Investors Service and AA+ by Fitch IBCA.

The Consolidated Statement of Cash Flows on page 32 provides additional
information.

CAPITAL

State Street's objective is to maintain a strong capital base in order to
provide financial flexibility for its business needs, including funding
corporate growth and supporting customers' cash management needs.

As a state chartered bank and member of the Federal Reserve System, State Street
Bank and Trust Company, State Street's principal subsidiary, is regulated by the
Federal Reserve Board, which has established guidelines for minimum capital
ratios. State Street has developed internal capital adequacy policies to ensure
that State Street Bank meets or exceeds the level required for the "well
capitalized" category, the highest of the Federal Reserve Board's five capital
categories. State Street's capital management emphasizes risk exposure rather
than simple asset levels; at 12.9%, State Street Bank's Tier 1 risk-based
capital ratio significantly exceeds the regulatory minimum of 4% and is among
the highest for U.S. banks. State Street's Tier 1 risk-based capital ratio of
14.1% is likewise among the highest for U.S. bank holding companies. See Note K
to the Consolidated Financial Statements, on page 40, for further information.

In May 1998, State Street issued $150 million of 30-year, floating-rate capital
securities, redeemable at the option of State Street in ten years. See Note H to
the Consolidated Financial Statements, on page 37, for further information.

The Board of Directors has authorized the purchase of State Street common stock
for use in employee benefit programs and for general corporate purposes. State
Street purchased 1.7 million shares in 1998. As of December 31, 1998, an
additional 3.3 million shares may be purchased within the stock purchase
program. See Note I to the Consolidated Financial Statements, on page 38, for
further information.

RISK MANAGEMENT
- --------------------------------------------------------------------------------
In providing services for institutional investors globally, State Street must
manage and control certain inherent risks. These include counterparty risk,
credit risk, fiduciary risk, operations and settlement risk, and market risk.
Risk management is an integral part of State Street's business activities and is
centrally organized with close ties to the business units. This structure allows
for corporate risk management across the business areas while individual line
areas remain responsible for risk management in their units.

Risk management emphasizes establishing specific authorization levels and
limits. Exposure levels are reviewed and modified as required by changing
conditions. Business-risk concentration analysis includes specific industry
lending concentrations, country limits, and individual counterparty limits. In
managing country risk, State Street considers a variety of issues, including
those related to credit quality, asset concentration, liquidity and transfer
risk.

Credit risk results from the possibility that a loss may occur if a counterparty
becomes unable to meet the terms of a contract. State Street has policies and
procedures to monitor and manage all aspects of credit risk. These include a
comprehensive credit-review and approval process that involves the assignment of
risk ratings to all loans and off-balance sheet credit exposures. Rigorous
credit approval processes cover traditional credit facilities, foreign exchange,
placements, credit-enhancement services, securities lending and
securities-clearing facilities.

Fiduciary risk is the risk of financial loss as a consequence of breaching a
fiduciary duty to a customer. Business units are responsible for operating
within the rules and regulations applicable to their businesses, including any
corporate guidelines. The Corporate Fiduciary Review Committee and the
Compliance Committee work with the business units to oversee adherence to
corporate standards.

State Street is a large servicer and manager of financial assets on a global
scale, so management of operations and settlement risk is an integral part of
the management process throughout the Corporation. State Street focuses on
payment-system risk management, overdraft monitoring and control, and global
securities clearing and settlement. In addition to specific authorization levels
and limits, operating risk is minimized by automation, standardized operating
procedures and insurance.

MARKET RISK: FOREIGN EXCHANGE AND
INTEREST RATE SENSITIVITY

State Street engages in trading and investment activities to serve customers'
investment and trading needs, contribute to overall corporate earnings, and
enhance liquidity. In the conduct of these activities, the Corporation is
subject to, and assumes, market risk. Market risk is the risk of an adverse
financial impact from changes in market prices, such as interest rates and
foreign exchange rates. The level of risk State Street assumes is a function of
the Corporation's overall objectives and liquidity needs, customer requirements,
and market volatility.

State Street manages its overall market risk through a comprehensive risk
management framework that includes a market risk management group that reports
independently to senior management. Market risk from foreign exchange and
trading activities is controlled through established limits on aggregate and net
open positions, sensitivity to changes in interest rates, and concentrations.
These limits are supplemented by stop-loss thresholds. The Corporation uses a
variety of risk

management tools and techniques, including value at risk, to measure, monitor
and control market risk. All limits and measurement techniques are reviewed and
adjusted as necessary on a regular basis by business managers, the market risk
management group and senior management.

State Street uses foreign exchange contracts and a variety of financial
derivative instruments to support customers' needs, conduct trading activities,
and manage its interest rate and currency risk. These activities are designed to
create trading revenue or hedge net interest revenue. In addition, the
Corporation provides services related to derivative instruments in its role as
both a manager and servicer of financial assets.

State Street's customers use derivatives to manage the financial risks
associated with their investment goals and business activities. With the growth
of cross-border investing, customers have an increasing need for foreign
exchange forward contracts to convert currency for international investment and
to manage the currency risk in international investment portfolios. As an active
participant in the foreign exchange markets, State Street provides foreign
exchange contracts and over-the-counter options in support of these customer
needs.

Trading Activities: Foreign Exchange and
Interest Rate Sensitivity

As part of its trading activities, the Corporation assumes positions in both the
foreign exchange and interest rate markets by buying and selling cash
instruments and using financial derivatives, including forward foreign exchange
contracts, foreign exchange and interest rate options, and interest rate swaps.
As of December 31, 1998, the notional amount of these derivative instruments was
$140 billion, of which $137 billion was foreign exchange forward contracts. Long
and short foreign exchange forward positions are closely matched to minimize
currency and interest rate risk. All foreign exchange contracts are valued daily
at current market rates.

The Corporation uses a variety of risk measurement and estimation techniques,
including value at risk. Value at risk is an estimate of potential loss for a
given period of time within a stated statistical confidence interval. State
Street uses a sophisticated risk management system, known as RiskBooktrademark
from Askari, Inc., to estimate value at risk daily for all material trading
positions. The Corporation has adopted standards for estimating value at risk,
and maintains capital for market risk, in accordance with the Federal Reserve's
Capital Adequacy Guidelines for market risk. Value at risk is estimated for a
99% one-tail confidence interval and an assumed one-day holding period using a
historical observation period of greater than one year. A 99% one-tail
confidence interval implies that daily trading losses should not exceed the
estimated value at risk more than 1% of the time, or approximately three days
out of the year. The methodology uses a simulation approach based on observed
changes in interest rates and foreign exchange rates and takes into account the
resulting diversification benefits provided from the mix of the Corporation's
trading positions.

Like all quantitative measures, value at risk is subject to certain limitations
and assumptions inherent to the methodology. State Street's methodology gives
equal weight to all market rate observations regardless of how recently the
market rates were observed. The estimate is calculated using static portfolios
consisting of positions held at the end of the trading day. Implicit in the
estimate is the assumption that no intraday action is taken by management during
adverse market movements. As a result, the methodology does not represent risk
associated with intraday changes in positions or intraday price volatility.

The following table presents State Street's market risk for its trading
activities as measured by its value at risk methodology:

State Street compares actual daily profit and losses from trading activities to
estimated one-day value at risk. During 1998, State Street experienced foreign
exchange trading losses in excess of its end of day value at risk estimate on
one occasion.

Non-Trading Activities: Currency Risk

State Street had approximately $15 billion of non-U.S. dollar denominated
non-trading assets as of December 31, 1998, which were primarily funded by
non-U.S. dollar denominated deposits. State Street's non-U.S. dollar denominated
non-trading assets consisted of 45 non-U.S. currencies. Approximately 90% of
these assets were in 15 major currencies. Since non-trading assets are generally
invested in the same currency in which the initial deposits are received, the
risk associated with changes to currency exchange rates is minimal. To the
extent that deposits are not reinvested in the same currency, the resulting net
currency positions are managed as part of the trading risk as discussed above.

In general, the maturities of these non-trading assets and liabilities are short
term. To the extent duration mismatches exist, they are managed as part of State
Street's consolidated asset/liability management activities and the related
market risk is included in the following non-trading interest rate sensitivity
disclosure.

Non-Trading Activities:
Interest Rate Sensitivity

The objective of interest rate sensitivity management is to provide sustainable
net interest revenue under various economic environments and to protect asset
values from adverse effects of changes in interest rates. State Street

- --------------------------------------------------------------------------------

<PAGE>

manages the structure of interest-earning assets and interest-bearing
liabilities by adjusting the mix, yields, and maturity or repricing
characteristics, based on market conditions. Since interest-bearing sources of
funds are predominantly short-term, State Street maintains a generally
short-term structure for its interest-earning assets, including money market
assets, investments and loans. Off-balance sheet financial instruments,
including interest rate swaps, are used minimally as part of overall asset and
liability management to augment State Street's management of interest rate
exposure. State Street uses three tools for measuring interest rate risk:
simulation, duration, and gap analysis.

Key assumptions in the simulation, duration and gap models include the timing of
cash flows, maturities and repricing of financial instruments, changes in market
conditions, loan volumes and pricing, capital planning, and deposit sensitivity.
These assumptions are inherently uncertain and as a result, the models cannot
precisely estimate net interest revenue or precisely predict the impact of
changes in interest rates on net interest revenue and economic value. Actual
results may differ from simulated results due to the timing, magnitude and
frequency of interest rate changes and changes in market conditions and
management strategies, among other factors.

Simulation models facilitate the evaluation of the potential range of net
interest revenue under "most likely" and alternative interest rate scenarios.
Based upon results of the simulation model as of December 31, 1998, which
reflects asset sensitivity beyond three months, the Corporation would expect an
increase in net interest revenue of $9 million over the following 12 months for
an immediate 100 basis points increase in interest rates. Conversely, if
interest rates immediately decreased by 100 basis points, the Corporation would
expect an $18 million decrease in net interest revenue.

Duration measures the change in the economic value of assets and liabilities for
given changes in interest rates. Based upon the results of the duration model as
of December 31, 1998, which indicates a close-to-neutral position, the
Corporation would expect an increase in the economic value of assets net of
liabilities of $12 million, or 0.03% of assets, as a result of an immediate
increase in interest rates of 100 basis points. In the event of an immediate
decrease of 100 basis points to interest rates, there is an expected decrease of
$15 million, or 0.03% of assets, to the economic value of assets net of
liabilities.

The third measure of interest rate risk, gap analysis, is the difference in
asset and liability repricing on a cumulative basis within a specified
timeframe. As of year-end 1998, interest-bearing liabilities reprice faster than
interest-earning assets over the next 12 months, as has been typical for State
Street. If all other variables remained constant, in the short term, falling
interest rates would lead to net interest revenue that is higher than it would
otherwise have been; rising rates would lead to lower net interest revenue.
Other important determinants of net interest revenue are rate levels, balance
sheet growth and mix, and interest rate spreads.

IN 1998 , State Street remained on course, achieving superior, long-term
performance by continuing to execute our strategic plan. We recorded strong
growth in revenue and earnings, achieving our 21st consecutive year of
double-digit earnings per share growth.

- --------------------------------------------------------------------------------
                                                                               5
<PAGE>

   This performance is a result of our strategic investments in the people and
   technology needed to promote revenue growth. We are continually developing
   the new, integrated products and services that institutional investors, our
   core customers, require. Our commitment to innovation is a key State Street
   strength. Powerful global financial trends, which we identified several years
   ago, are driving demand for our services.

   Worldwide, people are living longer. Aging populations are exerting pressure
   on pension systems, and causing individuals to think in terms of investing
   rather than saving. The quest for higher returns and lower risk is driving
   increased cross-border investing and more complex investment strategies. As
   discussed in "A Changing World," these demographic, social and market forces
   are driving demand for State Street's products and services.

FINANCIAL RESULTS State Street's primary financial goal is to achieve
   sustainable real growth in earnings per share. For 1998, earnings per share
   increased 15%, to $2.66. Our 15-year compound annual growth rate is 16%. Our
   supporting goals are to repeat our revenue growth rate of the
   1980s-annualized revenue growth of 12.5%, adjusted for inflation-in the
   1990s; and to achieve superior, long-term return on equity, which we have
   defined as 18%. Revenue for 1998 increased 18%, to $2.8 billion, contributing
   to a compound annual growth rate for the decade to date of 16.9% nominal, or
   14.4% real (inflation-adjusted). Return on equity for the year was 20.2%,
   exceeding our goal.

   A primary driver of revenue growth in 1998 was our new business success.
   Existing customers expanded their relationships with us, using additional
   services or assigning us responsibility for additional assets or funds. We
   also established many significant new relationships. This sales success helps
   maintain our momentum.

INVESTING AHEAD IN TECHNOLOGY AND PRODUCTS Revenues are a key determinant of
   earnings per share growth; as such, developing our revenue streams is a
   management focus. Providing value-added products and services is an important
   component of that effort. One of State Street's greatest strengths has been
   our consistent ability to anticipate change. We are continuously investing in
   technology and people in order to develop essential tools before they are
   needed. Our commitment enables our customers to take advantage of changing
   industry dynamics.

   Technology leadership is one of State Street's key competitive advantages. We
   have pioneered products such as State Street Global Link,(SM) the first
   real-time, fully-integrated electronic currency and equity trading platform,
   which we deliver over Bridge Information Systems's terminals; and
   In~Sight,(SM) an application that facilitates decision making and strategic
   planning for pension plan sponsors and investment managers.

   During 1998, we introduced several important new products. These include risk
   management tools such as VaR Calculator II, SL PerformanceAnalyzer,(SM) the
   State Street Universe, and Askari RiskBook,(TM) all designed to help our
   customers make the complex business decisions required by today's investment
   environment. We continue to leverage the convenience and economy of the
   internet, incorporating web-based tools in our designs. This year, we
   launched the SSgA Advice Account,(SM) offering defined-contribution plan
   participants personalized retirement planning and investment advice; and
   State Street Prime-Meridian(TM) Browser ACH, one of the first browser-based
   payment systems.

   State Street receives considerable recognition for our technology
   achievements. This year, among the awards we won was the prestigious
   "Excellence in Technology Award" from the GartnerGroup, a leading information
   technology research and consulting firm. More important, our customers
   recognize that, by combining advanced technology with market expertise and
   global resources, State Street sets the standards for excellence through the
   full spectrum of the investment process. Cross-selling products and
   value-added services enable State Street to broaden customer relationships.
   In 1998, approximately 80% of revenue growth came from existing customers,
   with our top 1,000 customers using an average of 5.8 State Street products
   each, while our top 100 customers used an average of 10.2 each.

GLOBAL EXPANSION STRATEGY State Street's global expansion strategy is based on
   fulfilling the specialized needs of institutional investors worldwide. We are
   committed to serving our customers wherever they are, and wherever their
   assets are-in any market, in any currency. This year we recorded strong
   revenue growth from institutional investors based outside the United States,
   primarily driven by new business gains. We expanded our capabilities in these
   growing markets as well, establishing an investment trust management and
   investment advisory company in Japan and an integrated European bank. We
   completed our acquisition of a unit trust trusteeship business in the United
   Kingdom, an important step in a key market. There are now State Street
   offices in 60 cities in 24 countries, and our subcustodian network spans 86
   markets, serving the growing demand for our services around the world.

   We are committed to expanding our presence in the global market because we
   expect continued rapid growth in non-U.S. markets. We also continue to see
   strong opportunities in the United States, a broad, deep and innovative
   market for institutional investors. Indeed, our relationships with U.S.
   customers are an integral part of our worldwide expansion strategy-as these
   customers grow globally, State Street grows with them.

INITIATIVES FOR FUTURE GROWTH We continue to expand our customer base and
   relationships, our markets, and our product offerings. One of the keys to our
   future success will be building on our expertise in post-trade services, like
   accounting and custody, by adding products and services that address the
   pre-trade and trade segments of the investment cycle: research, analysis, and
   trade execution tools. The Global Link service suite is a major success in
   this endeavor. In 1999, we will continue to enhance that platform. In
   addition, we plan to begin trading via Bond Connect,(SM) our advanced,
   electronic-execution system for fixed income securities. For our investment
   management customers-institutions and individuals around the world-we will
   continue to expand our broad array of sophisticated investment strategies.

OUTLOOK FOR 1999 We made excellent progress on our Year-2000 program in 1998.
   Our focus for 1999 is on testing internal system compliance and validating
   systems from third-party vendors. In January, we accomplished our conversion
   goals related to the euro, the new European currency that is replacing 11
   existing currencies. During the year, we will work with our customers to
   perform the discretionary conversions remaining as the transition to the euro
   continues through 2002.

   Throughout 1999 and beyond, we will focus on five core requirements for our
   continued success. We will work to develop and refine our strong revenue
   flows; increase profit margins; develop and manage migration to technology
   platforms for the 21st century; manage our controlled expansion into the
   pre-trade and trade sectors of the investment process; and increase business
   from non-U.S. customers.

GLOBAL LEADERSHIP State Street has established a powerful, global franchise by
   focusing on serving institutional investors worldwide. Our market is growing,
   driven by fundamental, long-term trends. By focusing on successful execution
   of our strategic plan, we will continue creating value for stockholders.

   State Street's success is attributable to the efforts of 16,800 dedicated,
   talented employees. We applaud their work on behalf of our customers and our
   company. We thank you, our owners, as well. We look forward to rewarding your
   confidence and support with continued strong financial performance in the
   years ahead.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

State Street Corporation ("State Street" or the "Corporation"), is a financial
services corporation that provides integrated banking, global custody,
investment management, administration and securities processing services to both
U.S. and non-U.S. customers. State Street reports three lines of business.
Services for Institutional Investors include accounting, custody, daily pricing,
administration, foreign exchange, cash management and information services to
support institutional investors. Investment Management provides an extensive
array of services for managing financial assets worldwide for both institutional
and individual investors as well as recordkeeping, administration, and
investment services for defined contribution plans and other employee benefit
programs. Commercial Lending includes lending activities, and other banking
services for regional middle-market companies, companies in selected industries
and institutional investor customers.

The accounting and reporting policies of State Street and its subsidiaries
conform to generally accepted accounting principles. Significant policies are
summarized below.

Basis of Presentation. The consolidated financial statements include the
accounts of State Street and its subsidiaries, including its principal
subsidiary, State Street Bank and Trust Company ("State Street Bank"). The
preparation of financial statements requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates. All
significant intercompany balances and transactions have been eliminated upon
consolidation. The results of operations of businesses purchased are included
from the date of acquisition. Investments in 50%-owned affiliates are accounted
for using the equity method. Certain previously reported amounts have been
reclassified to conform to the current method of presentation.

For the Consolidated Statement of Cash Flows, State Street has defined cash
equivalents as those amounts included in the Consolidated Statement of Condition
caption, "Cash and due from banks."

The AICPA issued Statement of Position 98-1, "Accounting for the Costs of
Computer Software Developed or Obtained for Internal Use," in March 1998. State
Street adopted this standard effective January 1, 1999. State Street currently
expects the adoption of this statement to have a favorable impact on earnings in
1999.

Resale and Repurchase Agreements;
Securities Borrowed. State Street purchases U.S. Treasury and federal agency
securities ("U.S. government securities") under agreements to resell the
securities. These purchases are recorded as securities purchased under resale
agreements, an asset in the Consolidated Statement of Condition. State Street
can use these securities as collateral for repurchase agreements. State Street's
policy is to take possession or control of the security underlying the resale
agreement, allowing borrowers the right of collateral substitution and/or
short-notice termination. The securities are revalued daily to determine if
additional collateral is necessary from the borrower. State Street enters into
sales of U.S. government securities under repurchase agreements, which are
treated as financings, and the obligations to repurchase such securities sold
are reflected as a liability in the Consolidated Statement of Condition. The
dollar amount of U.S. government securities underlying the repurchase agreements
remains in investment securities.

Securities borrowed are recorded at the amount of cash collateral deposited with
the lender. State Street monitors its market exposure daily with respect to
securities borrowed transactions and requests that excess securities be returned
or that additional securities be provided as needed.

Securities. Debt securities are held in both the investment and trading account
portfolios. Debt and marketable equity securities that are classified as
available for sale are reported at fair value and the after-tax unrealized gains
and losses are reported in other comprehensive income, a component of
stockholders' equity. Securities classified as held to maturity are stated at
cost, adjusted for amortization of premiums and accretion of discounts. Gains or
losses on sales of available-for-sale securities are computed based on
identified costs and included in fee revenue. Trading account assets are held in
anticipation of short-term market movements and for resale to customers. Trading
account assets are carried at fair value with unrealized gains and losses
reported in other fee revenue.

Loans and Lease Financing. Loans are placed on a non-accrual basis when they
become 60 days past due as to either principal or interest, or when, in the
opinion of management, full collection of principal or interest is unlikely.
When the loan is placed on non-accrual, the accrual of interest is discontinued,
and previously recorded but unpaid interest is reversed and charged against
current earnings.

Leveraged leases are carried net of nonrecourse debt. Revenue on leveraged
leases is recognized on a basis calculated to achieve a constant rate of return
on the outstanding investment in the leases, net of related deferred tax
liabilities, in the years in which the net investment is positive. Gains and
losses on residual values of leased equipment sold are included in fee revenue.

<PAGE>

Allowance for Loan Losses. The adequacy of the allowance for loan losses is
evaluated on a regular basis by management. Factors considered in evaluating the
adequacy of the allowance include previous loss experience, current economic
conditions and adverse situations that may affect the borrowers' ability to
repay, timing of future payments, estimated value of underlying collateral and
the performance of individual credits in relation to contract terms, and other
relevant factors. The provision for loan losses charged to earnings is based
upon management's judgment of the amount necessary to maintain the allowance at
a level adequate to absorb probable losses.

Premises and Equipment. Buildings, leasehold improvements, computers, software
and other equipment are carried at cost less accumulated depreciation and
amortization. Depreciation and amortization charged to operating expenses are
computed using the straight-line method over the estimated useful life of the
related asset or the remaining term of the lease.

Currency Translation. The assets and liabilities of non-U.S. operations are
translated at month-end exchange rates, and revenue and expenses are translated
at average monthly exchange rates. Gains or losses from the translation of the
net assets of certain non-U.S. subsidiaries, net of any currency hedges and
related taxes, are reported in other comprehensive income. Gains or losses from
other translations are included in fee revenue.

Derivative Financial Instruments. State Street uses three methods to account for
derivative financial instruments: the deferral method, accrual method, and fair
value method.

Interest rate swaps that are entered into as part of interest rate management
are accounted for using the accrual method. Interest receivable or payable
payments under the terms of the interest rate swap are accrued over the period
to which the payment relates. The interest payments accrued and any fees paid at
inception are recorded as an adjustment to the interest revenue or interest
expense of the underlying asset or liability.

Other interest rate contracts that are used for balance sheet management are
accounted for under the deferral method. The basis of the contract is
capitalized and any gain or loss is deferred and amortized over the life of the
hedged asset or liability as an adjustment to the interest revenue or interest
expense.

The gross amount of unrealized gains and losses on foreign exchange and interest
rate contracts are reported separately as other assets and other liabilities,
respectively, in the Consolidated Statement of Condition, except where such
gains and losses arise from contracts covered by qualifying master netting
agreements.

SFAS No. 133, "Accounting for Derivative Instruments and Hedging Activities,"
was issued in June 1998. This statement requires companies to record the fair
value of derivatives on the balance sheet as assets or liabilities. Fair market
valuation adjustments for derivatives meeting hedge criteria will be recorded as
either other comprehensive income, or through earnings in the Consolidated
Statement of Income, depending on their classification. Derivatives used for
trading purposes will continue to be marked to market through earnings. State
Street will adopt this statement beginning January 1, 2000. Management does not
expect the adoption of this statement to have a material impact on the financial
statements.

Income Taxes. The provision for income taxes includes deferred income taxes
arising as a result of reporting some items of revenue and expense in different
years for tax and financial reporting purposes.

Earnings Per Share. Basic earnings per share excludes all dilution and is
computed by dividing income available to common stockholders by the weighted
average number of common shares outstanding for the period. Diluted earnings per
share reflects the potential dilution that could occur if stock options and
stock award grants were exercised. Diluted earnings per share also includes the
assumption that all convertible debt has been converted as of the beginning of
each period.

Comprehensive Income. Effective January 1, 1998, State Street adopted SFAS No.
130, "Reporting Comprehensive Income." Disclosures required by this standard are
presented in the Consolidated Statement of Changes in Shareholders' Equity and
Note Q to the Consolidated Financial Statements. Lines of Business. Effective
for the year ended December 31, 1998, State Street adopted the new disclosures
required by SFAS No. 131, "Disclosures about Segments of an Enterprise and
Related Information." The requirements of this standard are presented in Note O
to the Consolidated Financial Statements.

ACQUISITION

In November 1996, State Street acquired Princeton Financial Systems, Inc.
("PFS") for 1,846,000 shares of State Street's common stock and cash in a
transaction accounted for as a purchase. PFS provides services and client/server
software for investment managers with particular focus on the insurance
industry.

</TABLE>

State Street has entered into noncancelable operating leases for premises and
equipment. At December 31, 1998, future minimum payments under noncancelable
operating leases with initial or remaining terms of one year or more totaled
$1.0 billion. This consisted of $109 million, $100 million, $99 million, $92
million and $82 million for the years 1999 to 2003, respectively, and $565
million thereafter. The minimum rental commitments have been reduced by sublease
rental commitments of $31 million. Nearly all leases include renewal options.

Total rental expense amounted to $95 million, $64 million and $55 million in
1998, 1997 and 1996, respectively. Rental expense has been reduced by sublease
revenue of $4 million, $2 million and $1 million for the years ended December
31, 1998, 1997 and 1996, respectively.

SECURITIES SOLD UNDER REPURCHASE AGREEMENTS

State Street enters into sales of U.S. government securities under repurchase
agreements that are treated as financings, and the obligations to repurchase
such securities sold are reflected as a liability in the Consolidated Statement
of Condition. The dollar amount of U.S. government securities underlying the
repurchase agreements remains in investment securities.

Information on these U.S. government securities, and the related repurchase
agreements including accrued interest, is shown in the following table. This
table excludes repurchase agreements that are secured by securities purchased
under resale agreements and securities borrowed.

State Street has established three statutory business trusts, which collectively
issued $650 million of cumulative semi-annual income and quarterly income
preferred securities ("capital securities"). The capital securities qualify as
Tier 1 capital under federal regulatory guidelines. The proceeds of these
issuances along with proceeds of related issuances of common securities of the
trusts, were invested in junior

subordinated debentures ("debentures") of State Street. The debentures are the
sole assets of the trusts. State Street owns all of the common securities of the
trusts.

Payments to be made by the trusts on the capital securities are dependent on
payments that State Street has committed to make, particularly the payments to
be made by State Street on the debentures. Compliance by State Street would have
the effect of providing a full, irrevocable and unconditional guarantee of the
trusts' obligations under the capital securities.

Distributions on the capital securities are included in interest expense and are
payable from interest payments received on the debentures and are due
semi-annually for capital securities A and B and quarterly for Capital Trust I,
subject to deferral for up to five years under certain conditions. The capital
securities are subject to mandatory redemption in whole at the stated maturity
upon repayment of the debentures; with the optional redemption at any time by
State Street of the debentures upon the occurance of certain tax events or
changes to tax treatment, investment company regulation or capital treatment
changes; or at any time after March 15, 2007 for the Capital Securities B, after
December 30, 2006 for the Capital Securities A and after May 15, 2028 for the
Capital Trust I securities.

For Capital Securities A and B, redemptions are based on declining redemption
prices according to the terms of the trust agreements. All redemptions are
subject to federal regulatory approval.

In April 1996, a shelf registration statement became effective that allowed
State Street to issue up to $500 million of unsecured debt securities or shares
of its preferred stock or both. In June 1996, State Street issued $150 million
of 7.35% notes due 2026, redeemable at the option of the holder in 2006. In
April 1998, that registration statement was amended to also allow for issuance
of capital securities. In May 1998, State Street completed the sale of $150
million of floating rate capital securities issued by Capital Trust I. In
connection with the sale of these capital securities, State Street issued $150
million of floating rate junior subordinated deferrable interest debentures to
Capital Trust I due in May 2028. Subsequent to that issuance, two interest rate
swaps were entered into to, in effect, modify the interest expense from a
floating rate to a fixed rate of 6.58%. At December 31, 1998, $200 million of
the shelf registration was available for issuance.

The 5.95% notes are unsecured obligations of State Street.

The 9.50% mortgage note was fully collateralized by property at December 31,
1998. The scheduled principal payments for the next five years are $1 million
for the years 1999 and 2000 and $2 million for each year 2001 through 2003.

The 7.75% debentures are convertible to common stock at a price of $2.875 per
share, subject to adjustment for certain events. The debentures are redeemable
at par, at State Street's option. During 1998 and 1997, debentures were
converted into 144,345 and 168,692 shares of common stock, respectively. At
December 31, 1998, 793,046 shares of common stock had been reserved for issuance
upon conversion.

STOCKHOLDERS' EQUITY

In May 1997, State Street distributed to stockholders a two-for-one stock split
in the form of a 100% stock dividend. The par value of these additional shares
was capitalized by a transfer from retained earnings to common stock. Prior
period share and per share amounts have been restated for the stock split.

During 1998, the Board of Directors increased the number of shares of State
Street common stock authorized for purchase from 12 million to 14 million
shares. Shares purchased under the authorization can be used for employee
benefit plans and general corporate purposes. During 1998 and 1997, State Street
purchased 1,716,000 and 2,760,000 shares of its common stock, respectively, at
an average cost of $58 and $40 per share, respectively. As of December 31, 1998,
total shares purchased were 10,706,000.

Under the 1997 Equity Incentive Plan, stock options, stock appreciation rights
("SARs"), restricted and unrestricted stock awards, deferred stock awards, and
performance awards covering 8,000,000 shares of common stock may be issued.


Under this long-term incentive plan, the exercise price of non-qualified and
incentive stock options may not be less than the fair value of such shares at
the date of grant and expire no longer than ten years from the date of grant.
Performance awards have been granted to officers at the policy-making level.
Performance awards are earned over a performance period based on achievement of
goals. Payment for performance awards is made in cash equal to the fair market
value of State Street's common stock after the conclusion of each performance
period. During 1998, 479,000 performance awards were granted. In 1998 and 1997,
284,000 and 351,000 restricted stock awards, net of cancellations, respectively,
were granted under the stock award program.

In addition, State Street has a stock award program consisting of 600,000 shares
vesting 20% per annum commencing January 1, 2001.

Compensation expense related to performance awards, restricted stock awards and
stock awards was $38 million, $29 million and $19 million for 1998, 1997 and
1996, respectively.

In 1996, 1,066,000 options were exercised at per share prices of $2.81 to
$14.53. At December 31, 1998, a total of 2,617,000 shares under options were
exercisable. At December 31, 1998, 3,372,000 shares under the 1997 Equity
Incentive Plan were available for future grants.

Pro forma results of net income and earnings per share using the fair value
method for accounting for stock-based employer compensation plans for the years
ended December 31, 1998, 1997 and 1996 are not presented, as results differ by
three percent or less from those reported. For purposes of the pro forma
calculation, the estimated fair value of the options is amortized to expense
over the options vesting period.

For purposes of estimating the fair value of State Street's employee stock
options at the grant date, a Black-Scholes option pricing model was used.
Following are the weighted average assumptions for 1998, 1997 and 1996,
respectively: risk-free interest rates of 5.15%, 6.22% and 6.41%; dividend
yields of .86%, 1.05% and 1.51%; and volatility factors of the expected market
price of State Street common stock of .29, .28 and .25. The weighted average
life of the stock options granted is 4.2, 5.5 and 6.6 years for the years ended
December 31, 1998, 1997 and 1996, respectively.

SHAREHOLDERS' RIGHTS PLAN

In 1988, State Street declared a dividend of one preferred share purchase right
for each outstanding share of common stock. On June 18, 1998, State Street
adopted an amendment to the Rights Agreement and has restated the Rights
Agreement. Under the Amended and Restated Rights Agreement, a right may be
exercised, under certain conditions, to purchase one four-hundredths share of a
series of participating preferred stock at an exercise price of $265, subject to
adjustment. The rights become exercisable if a party acquires or obtains the
right to acquire 10% or more of State Street's common stock or after
commencement or public announcement of an offer for 10% or more of State
Street's common stock. When exercisable, under certain conditions, each right
also entitles the holder thereof to purchase shares of common stock, of either
State Street or of the acquiror, having a market value of two times the then
current exercise price of that right.

The rights expire in September 2008, and may be redeemed at a price of $.0025
per right at any time prior to expiration or the acquisition of 10% of State
Street's common stock. Under certain circumstances, the rights may be redeemed
after they become exercisable and may be subject to automatic redemption.

                                                                              39

REGULATORY MATTERS

Regulatory Capital. State Street is subject to various regulatory capital
requirements administered by the federal banking agencies. Failure to meet
minimum capital requirements can initiate certain mandatory and discretionary
actions by regulators that, if undertaken, could have a direct material effect
on State Street's financial statements. Under capital adequacy guidelines, State
Street must meet specific capital guidelines that involve quantitative measures
of State Street's assets, liabilities and certain off-balance sheet items as
calculated under regulatory accounting practices. State Street's capital amounts
and classification are also subject to qualitative judgments by the regulators
about components, risk weightings and other factors.

Quantitative measures established by regulation to ensure capital adequacy
require State Street and State Street Bank to maintain minimum risk-based and
leverage ratios as set forth in the table below. The risk-based capital ratios
are Tier 1 capital and Total capital to total adjusted risk-weighted assets and
market-risk equivalents, and the leverage ratio is Tier 1 capital to quarterly
average assets.

As of December 31, 1998, State Street Bank was categorized as well capitalized
under the regulatory framework for prompt corrective action. To be categorized
as well capitalized, State Street Bank must exceed the well capitalized
guideline ratios, as set forth in the table, and meet certain other
requirements. Management believes that State Street Bank exceeds all well
capitalized requirements, and there have been no conditions or events since
year-end that management believes would change the status of well capitalized.

The regulatory capital amounts and ratios were the following at December 31:

</TABLE>

(1) The regulatory designation of "well capitalized" under prompt corrective
    action regulations is not applicable to bank holding companies (State
    Street). Regulation Y defines well capitalized for bank holding companies
    (State Street) for the purpose of determining eligibility for a streamlined
    review process for acquisition proposals. For such purposes, well
    capitalized requires a minimum Tier 1 risk-based capital ratio of 6% and a
    minimum total risk-based capital ratio of 10%.

(2) Effective January 1, 1998, regulatory capital standards require the addition
    of market risk-equivalent assets to total risk-based assets.

Cash, Dividend, Loan and Other Restrictions. During 1998, subsidiary banks of
State Street were required by the Federal Reserve Bank to maintain average
reserve balances of $244 million. Federal and state banking regulations place
certain restrictions on dividends paid by subsidiary banks to State Street. At
December 31, 1998, State Street Bank had $979 million of retained earnings
available for distribution to State Street in the form of dividends.

The Federal Reserve Act requires that extensions of credit by State Street Bank
to certain affiliates, including State Street, be secured by specific
collateral, that the extension of credit to any one affiliate be limited to 10%
of capital and surplus (as defined), and that extensions of credit to all such
affiliates be limited to 20% of capital and surplus.

At December 31, 1998, consolidated retained earnings included $31 million
representing undistributed earnings of 50%-owned affiliates that are accounted
for using the equity method.

State Street has a committed line of credit of $50 million to support its
commercial paper program.

If the health care cost trend rates were increased by 1%, the postretirement
benefit obligation as of December 31, 1998, would have increased 4%, and the
aggregate expense for service and interest costs for 1998 would have increased
by 6%. Conversely, if the health care cost trend rates were decreased by 1%, the
postretirement benefit obligation as of December 31, 1998, would have decreased
4%, and the aggregate expense for service and interest costs for 1998 would have
decreased by 5%.

Employees of State Street Bank and certain subsidiaries are eligible to
contribute a portion of their pre-tax salary to a 401(k) savings plan. State
Street matches a portion of these contributions, and the related expense was $11
million for 1998 and 1997 and $9 million for 1996.

Current and deferred taxes for 1997 and 1996 have been reclassified to reflect
the tax returns as actually filed. Income tax benefits recorded directly to
stockholders' equity for the years 1998, 1997 and 1996 included $24 million, $10
million and $7 million, respectively, related to employee stock option exercises
and other stock transactions. A benefit of $4 million and $3 million and an
expense of less than $1 million related to fair value adjustments for the
investment portfolio were included in other comprehensive income for the years
1998, 1997 and 1996, respectively. An expense of $4 million for 1998 and
benefits of $3 million and $1 million for 1997 and 1996, respectively, relating
to foreign currency translation adjustments were included in other comprehensive
income. These taxes are not included in the preceding table.

Income tax expense related to net securities gains was $4 million, $1 million
and $2 million for 1998, 1997 and 1996, respectively.

Pre-tax income attributable to operations located outside the United States was
$80 million, $85 million and $42 million in 1998, 1997 and 1996, respectively.

At December 31, 1998, State Street had U.S. alternative minimum tax credit
carryforwards of $9 million and non-U.S. tax loss carryforwards of $5 million.
If not used, $3 million of the non-U.S. tax losses will expire in the years 2000
and 2001. Remaining tax losses and alternative minimum tax credits carry forward
indefinitely.

CONTINGENT LIABILITIES

State Street provides banking, trust, investment management, global custody,
accounting, administration and securities processing services to both domestic
and non-U.S. customers. Assets under custody and assets under management are
held by State Street in a fiduciary or custodial capacity and are not included
in the Consolidated Statement of Condition because such items are not assets of
State Street. Management conducts regular reviews of its responsibilities for
these services and considers the results in preparing its financial statements.
In the opinion of management, there are no contingent liabilities at December
31, 1998, that would have a material adverse effect on State Street's financial
position or results of operations.

State Street is subject to pending and threatened legal actions that arise in
the normal course of business. In the opinion of management, after discussion
with counsel, these actions can be successfully defended or resolved without a
material adverse effect on State Street's financial position or results of
operations.

OFF-BALANCE SHEET FINANCIAL INSTRUMENTS,
INCLUDING DERIVATIVES

An off-balance sheet derivative instrument is a contract or agreement whose
value is derived from interest rates, currency exchange rates or other financial
indices. Derivative instruments include forwards, futures, swaps, options and
other instruments with similar characteristics. The use of these instruments
generates fee, interest or trading revenue.

Interest rate contracts involve an agreement with a counterparty to exchange
cash flows based on the movement of an underlying interest rate index. An
interest rate swap agreement involves the exchange of a series of interest
payments, either at a fixed or variable rate, based upon the notional amount
without the exchange of the underlying principal amount. An interest rate option
contract provides the purchaser, for a premium, the right, but not the
obligation, to buy or sell the underlying financial instrument at a set price at
or during a specified period. An interest rate futures contract is a commitment
to buy or sell, at a future date, a financial instrument at a contracted price;
it may be settled in cash or through the delivery of the contracted instrument.

Foreign exchange contracts involve an agreement to exchange the currency of one
country for the currency of another country at an agreed-upon rate and
settlement date. Foreign exchange contracts consist of swap agreements and
forward and spot contracts.

The following table summarizes the contractual or notional amounts of derivative
financial instruments held or issued by State Street for trading and balance
sheet management at December 31:

</TABLE>

State Street's risk exposure from interest rate and foreign exchange contracts
results from the possibility that one party may default on its contractual
obligation or from movements in exchange or interest rates. Credit risk is
limited to the positive market value of the derivative financial instrument,
which is significantly less than the notional value. The notional value provides
the basis for determining the exchange of contractual cash flows. The exposure
to credit loss can be estimated by calculating the cost, on a present value
basis, to replace at current market rates all profitable contracts at year end.
The estimated aggregate replacement cost of derivative financial instruments in
a net positive position was $1.6 billion and $1.4 billion at December 31, 1998
and 1997, respectively.

Net foreign exchange trading revenue related to foreign exchange contracts
totaled $289 million, $245 million and $126 million for 1998, 1997 and 1996,
respectively. Gains for other financial instrument contracts were $3 million in
1998 and $1 million in 1997 and 1996. Future cash requirements, if any, related
to foreign currency contracts are represented by the gross amount of currencies
to be exchanged under each contract unless State Street and the counterparty
have agreed to pay or receive the net contractual settlement amount on the
settlement date. Future cash requirements on other financial instruments are
limited to the net amounts payable under the agreements.

Credit-related financial instruments include indemnified securities on loan,
commitments to extend credit, standby letters of credit and letters of credit.
The maximum credit risk associated with credit-related financial instruments is
measured by the contractual amounts of these instruments.

The following is a summary of the contractual amount of State Street's
credit-related, off-balance sheet financial instruments at December 31:

On behalf of its customers, State Street lends their securities to creditworthy
brokers and other institutions. In certain circumstances, State Street may
indemnify its customers for the fair market value of those securities against a
failure of the borrower to return such securities. State Street requires the
borrowers to provide collateral in an amount equal to or in excess of 102% of
the fair market value of the securities borrowed. The borrowed securities are
revalued daily to determine if additional collateral is necessary. State Street
held, as collateral, cash and U.S. government securities totaling $68 billion
and $59 billion for indemnified securities on loan at December 31, 1998 and
1997, respectively.

Loan commitments (unfunded loans, asset purchase agreements and unused lines of
credit), standby letters of credit and letters of credit are issued to
accommodate the financing needs of State Street's customers. Loan commitments
are agreements by State Street to lend monies at a future date, or agreements to
purchase assets, subject to conditions established in the agreement. Standby
letters of credit and letters of credit commit State Street to make payments on
behalf of customers when certain specified events occur.

These loan and letter of credit commitments are subject to the same credit
policies and reviews as loans. The amount and nature of collateral is obtained
based upon management's assessment of the credit risk. Approximately 75% of the
loan commitments expire within one year from the date of issue. Since many of
the commitments are expected to expire without being drawn, the total commitment
amounts do not necessarily represent future cash requirements.

- --------------------------------------------------------------------------------
NOTE U
- --------------------------------------------------------------------------------
FAIR VALUE OF FINANCIAL INSTRUMENTS

State Street uses the following methods to estimate the fair value of financial
instruments.

For financial instruments that have quoted market prices, those quotes are used
to determine fair value. Financial instruments that have no defined maturity,
have a remaining maturity of 180 days or less, or reprice frequently to a market
rate, are assumed to have a fair value that approximates reported book value,
after taking into consideration any applicable credit risk. If no market quotes
are available, financial instruments are valued by discounting the expected cash
flow(s) using an estimated current market interest rate for the financial
instrument. For off-balance sheet derivative instruments, fair value is
estimated as the amount that State Street would receive or pay to terminate the
contracts at the reporting date, taking into account the current unrealized
gains or losses on open contracts.

- --------------------------------------------------------------------------------
                                                                              45

The short maturity of State Street's assets and liabilities results in having a
significant number of financial instruments whose fair value equals or closely
approximates reported balance sheet value. Such financial instruments are
reported in the following balance sheet captions: cash and due from banks,
interest-bearing deposits with banks, securities purchased under resale
agreements and securities borrowed, federal funds sold, deposits, securities
sold under repurchase agreements, federal funds purchased, and other short-term
borrowings. Fair value of trading accounts equals the balance sheet value. As of
December 31, 1998 and 1997, the fair value of interest rate contracts used for
balance sheet management were a payable of $8 million and $4 million,
respectively. There is no reported cost for loan commitments.

The reported value and fair value for other balance sheet captions at December
31, are as follows:

NON-U.S. ACTIVITIES

Non-U.S. activities, as defined by the Securities and Exchange Commission, are
considered to be those revenue-producing assets and transactions that arise from
customers domiciled outside the United States. Due to the nature of State
Street's business, it is not possible to segregate precisely domestic and
non-U.S. activities. The determination of earnings attributable to non-U.S.
activities requires internal allocations for resources common to non-U.S. and
domestic activities. Subjective judgments have been used to arrive at the
operating results for non-U.S. activities. Interest expense allocations are
based on the average cost of short-term borrowed funds. Allocations for
operating expenses and certain administrative costs are based on services
provided and received.

The following table summarizes non-U.S. operating results and assets, based on
the domicile location of customers, for the years ended and as of December 31:

REPORT OF INDEPENDENT AUDITORS
- --------------------------------------------------------------------------------

The Stockholders and Board of Directors
State Street Corporation

We have audited the accompanying consolidated statements of condition of State
Street Corporation (Corporation) as of December 31, 1998 and 1997, and the
related consolidated statements of income, cash flows and changes in
stockholders' equity for each of the three years in the period ended December
31, 1998. These financial statements are the responsibility of the Corporation's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to herein present fairly, in
all material respects, the consolidated financial position of State Street
Corporation at December 31, 1998 and 1997, and the consolidated results of its
operations and its cash flows for each of the three years in the period ended
December 31, 1998 in conformity with generally accepted accounting principles.
